Optimize Your BitTorrent Download Speed
BitTorrent can be fun, as long as you get decent speeds. Not satisfied with your current speeds? These suggestions might help to optimize your download pleasure
1. Hack the max half-open TCP connections
If you’re on XP sp2, your TCP connections are limited to a maximum of 10. This might hurt your downloading speed because it wont let you connect to as much peers as you want. It is supposed to slow down viruses because their spreading strategy is to connect to a high amount of ip numbers, but it could cripple your torrent downloads.
A nice way to fix this is to download this patch.
Note: Some people report that their antivir reports the patch to be a Virus, This is not the case. Check out http://www.lvllord.de/ for more details on this
The patch allows you to set the maximum allowed connections to any number you want. Any number between 50 and 100 is ok (more is NOT always better).
Next you need to configure your torrent client to allow 50-100 max half-open TCP connections
uTorrent: Options > Preferences > Advanced options > net.max_halfopen
Bitcomet: Options > Preferences > Connection > max half-open TCP
Now you’re ready to go…
A third point of interest is that some “windows updates” revert your tweaked tcp connections back to 10. So it’s wise to check this every now and then. You can check this by going to (in windows xp) Start > Control Panel > Administrative Tools > Event Viewer > System… Look for event 4226 (sort by event).
For more details about Windows XP SP2 and Event ID 4226 read David Kaspar’s excellent post
If there are a lot of daily occurences it’s likely that the max amount of half-open tcp connections was set back to 10. Or you’re infected with some nasty spyware…
2. Torrent Client Configuration
In order to apply these tips you need to know your maximum up- and download speed. You can test your bandwidth over here (stop all download activity while testing). Also make sure that you applied the tips provided in our previous posts.
Note that there’s a difference between kb/s (kilobits/second) and kB/s (kilobytes/second). To be precise, kB/s = kb/s divided by 8. In this tutorial we use kB/s (like most torrent clients do). This means that you might need to calculate your max speed in kB/s yourself if the speedtest only gives you the results in kb\s (so divide by 8 then).
Settings 1-4 can be found in the options, settings or preference tab of most torrent clients.
1. Maximum upload speed
Probably the most important setting there is. Your connection is (sort of) like a pipeline, if you use you maximum upload speed there’s not enough space left for the files you are downloading. So you have to cap your upload speed.
Use the following formula to determine your optimal upload speed…
80% of your maximum upload speed
so if your maximum upload speed is 40 kB/s, the optimal upload rate is 32kB/s
But keep seeding!
2. Maximum download speed
Although setting your maximum download speed to unlimited may sound interesting, in reality it will only hurt your connection. If you still want to be able to browse properly, set your maximum download speed to:
95% of your maximum download speed
so if your maximum download speed is 400 kB/s, the optimal download speed is 380kB/s
3. Maximum connected peers per torrent
Yet another setting that you don’t want to max out. I experimented quite a lot with the max connected peers settings and came to the conclusion that both high and low number hurt the download speed of a torrent. The following setting worked best for me.
upload speed * 1.3
so if your maximum upload speed is 40 kB/s, the optimal amount of connected peers per torrent is
40 * 1.3 = 52
I didn’t noticed a difference for fast or slow connections here.
4. Maximum upload slots
1 + (upload speed / 6)
so if your maximum upload speed is 30 kB/s, the optimal number of upload slots is
1 + (30 / 6) = 6
3. More Tips
Check seeds and peers
A simple tip, but very important. Always look for torrents with the best seed/peer ratio. The more seeds (compared to peers) the better (in general). So 50 seeds and 50 peers is better than 500 seeds and 1000 peers. So, be selective.
Change the default port.
By default, BitTorrent uses a port 6881-6999. BitTorrent generates a lot traffic (1/3), so isp’s like to limit the connection offered on the these ports. So, you should change these to another range. Good clients allow you to do this, just choose anything you like. If you’re behind a router, make sure you have your ports forwarded (portforward.com) or UPnP enabled.
Disable Windows Firewall
It sucks. Windows Firewall hates P2P and often leads a life of it’s own. So disable it and get yourself a decent (free) firewall, Kerio or Zone Alarm for example.
Turn on Encryption
Encrypting your torrents will prevent throttling ISP’s from limiting your BitTorrent traffic. Check out how to enable encryption in Azureus, uTorrent, and Bitcomet, the three most popular torrent clients.
Optimize your internet connection
The TCP optimizer is a freeware utility that optimizes your internet connection. I found it very useful and it helped speeding up my connection for regular internet activity and for downloading torrents. Just download it, and move the slidebar to your maximum download rate (note that it’s in kb/s). Don’t try to set it higher because that will hurt your download speeds!
Last but not least… Buy a faster connection…
Happy Torrenting!

re: point #1 — it says “half-open” connections — this does not mean you can only have 10 connections at a time: it means you can only have ten connection _attempts in progress_ at any one time. You can still have hundreds of peers connected, but the rate at which you may connect is slowed down. It does not cripple torrents, it merely slows down the spin up time, albeit marginally.
why are you d/l a patch with a backdoor virus
a virus? Are you sure? That would be awesome. Just what I’d need.
Great article dude. I will be sure to pass this on to others.
Great article. Little bit of a typo though.
If you still want to be able to browse properly, set your maximum download speed to:
95% of your maximum upload speed
so if your maximum download speed is 400 kB/s, the optimal download speed is 380kB/s
Should say 95% of your maximum download speed.
Thanks for the torrent tips, Cool Page!
digg ROCKS!
Backdoor program BDS/Virkel.A.7 was detected by my AntiVir.
It’s best to find a tutorial which shows you how to do it without downloading some random patch being hotlinked anyway. Just seeing the link sitting there made me feel uneasy about it.
My AV didn’t find a virus, but I foolishly ran the evid4266 patch *before* I read all the comments. I think/hope I undid all the changes correctly.
Anybody wanna do some research and confirm the virus issue one way or the other?
great article one question. Does Vista also limit the connections to 10? I’m using the public beta and that tool doesn’t work(obviously).
Nice article ..except for this slight mistake “kb/s = kB/s divided by 8″ … It should have been :
“kb/s = kB/s multiplied by 8″ or
“kB/s = kb/s divided by 8″
Those previous comments involving antivir were most likely false positives on the virus scan. I as well as several others have scanned with our respective programs and found nothing strange, plus we’ve been using it for ages.
…um…ok, I used that patch, but I don’t know how to undo it. Help please?
Nick and Sachin, thanks for pointing out the inconsistencies: corrected!
Zero, the patch is perfectly safe and you can undo it by running the patch again and changing to max connections to 10.
About the patch being a virus, this is not the case:
“So 50 seeds and 50 peers is better than 500 seeds and 1000 peers”
500 seeds and 1000 peers would almost always be the faster download - remember all those peers are seeders too
UPnP for port forwarding? NO
[quote]500 seeds and 1000 peers would almost always be the faster download - remember all those peers are seeders too[/quote]
A peer is not a seeder. And torrents with a higher “seed / peer ratio” tend to be healthier.
sure it depends on the % of the complete file the leechers (peers) have on average. The download will probably be faster if all peers are on 95%, but it will be slower if the peers are on 5%. The example is just to sress that it is important to take a look at the the seed / peer ratio.
Im gona totally try these methods! Thanks for the great post
“A peer is not a seeder”
if a peer is not seeding it obviously isn’t taxing your download either…so it wouldn’t be much of a peer.
“And torrents with a higher “seed / peer ratio” tend to be healthier.”
but torrents with a higher number of connections (from EITHER seeds or peers) will generally be faster (assuming one good seed).
now, small files WILL benefit from a high-seed-ratio….but small files should be fast anyway
“but torrents with a higher number of connections (from EITHER seeds or peers) will generally be faster (assuming one good seed).”
that’s true if the seed has unlimited upload bandwith available, but on average it isn’t.
compare these 2 cases, lets assume all seeds and peers have 100up and 200down:
1. 10 seeds and 10 peers
2. 100 seeds and 200 peers
In the most ideal situation the peers in case 1 will download at full speed and max out their connection (200). However, in case 2 the peers will only get 150 in the most ideal setting.
This is oversimplified, but it’s just the way it is
I have a problem with utorrent 1.5.1 lots of hash fails are happening at my place if somebody can help me how to reduce it thier help is welcome
Iceman: It’s good to hear something from you other that bashing… ;)
1. Does it happen with all torrents? Even with linux distro’s? It could be a corrupt torrent
2. What router do you have? D-link?
3. Have you tried to upgrade to the latest RC?
I use utorrent and for me is the best torrent software!! Only 155Kb of software and 3,9Mb in RAM… WOW!!!
Is the max half-open TCP connections issue exclusively on SP2? Are there any SP1 patches that do the same thing?
dis is a repeat blog of one posted ages ago…
Good Job.. The Patch is not a virus? Who posted that 1? lol
If any of you knew ANYTHING about TCP/IP settings… and how programs communicate with the internet, you would know your virus scanner is going to freak out on ANY program that tampers with such delecate settings… The patch is NOT a virus, nore a backdoor trojen. Nice tutorial. Actually increased Torrent speed slightly with a 1.2MB/s connection.
how do u change the half open option on azureus?or can yer?cheers
I use bitcomet, but I don’t know what is “Maximum connected peers” in Bitcommet, someone help me pls!.
what is “Max sessions per IP downloading(uploading) task”? it had already set 3 and 1
[half-open tcp conenctions]
1) dis dont work on vista and prob. never will.
2) dis dont increase torrent download speed. it decreases time 2 start downloading cos wen u r downloading, u have completed connections, dey r not 1/2 open anymore.
Reguardless of what people have posted about the virus I went ahead and installed the patch. and all I have to say is
Thnak You My torrents unfroze and are working the way they should.
great help but problem in port forwarding , as iam using emule and it also needs port forwarded so how can i map 2 port nos(1 for emule tcp and 1 for torrent)in tcp as it can forward 1 port.
???
1 byte = 8 bits! Look anywhere on the internet for that…
So kb/s = kB/s divided by 8, that is obvious and correct, ‘kB/s = kb/s multiplied by 8′ is also correct, not the reverse…
123
máš to zavirovaný buzíku
1 feet = 12 inch
36 inch = 36/12 = 3 feet
concept obviously same as bytes and bits
therefore kB/s = kb/s divided by 8
i did all that and it did not help my speeds at all!!!
Amazing article. Cleared out some of the questions i had in mind. Thank you very much.
Same as sam…
Anything else we could take into consideration?Like keeping the least open tasks at any time?

I’d take you seriously if you didn’t type like you had a mental disease.
how do you change the settings changed by the patch manually!
the patch is a real virus!!!. I ran that patch and I relize this patch automatic copy itself to Temp folder and other folder in my computer, I can’t delete them, some of them visible while some invisible, I only see them by seach tools. Be careful guys! good luck!!!
Wow man thank you so much, after encryption my dl speed instantly tripled, F my ISP for capping my BT without telling me.
This is a really great site. Thanks! I ll be back soon!
“how do you change the settings changed by the patch manually!”
That is exactly what I was wondering. I bet it can’t be too complicated to manually do, so lets see it! Forget this file that might be a vivrus, how about sharing the source or how it can be done manually!
Hey can someone explain what is the purpose of changing the net.max_halfopen from default 8 to 80? i have tried downloading with both configurations and haven’t really noticed a big speed increase from the default 8 to the change of 80, sometimes it seemed even faster at the default setting, so if anyone knows about this net.max_halfopen, please explain in the simplest terms possible. Thx. I have already changed the TCP part of winxp sp2 and i notice the speed increase from that change.
BEWARE! CRASHED WINDOWS,needed to reinstall windows after following above info.

Try it with VLC media player
hai.. i’ve tried the download/upload test and it says that my download speed is lower than my upload speed. I wondered why cos my DSL line speed should be around 100.0 Mbps..Any help pls..thks!
i followed this guide precisely and although it did improve my speed the diffence between before and after is not much. So could it be that i might of done something wrong or is there something else please help!
@Sachin:
Sorry to say but:
is also wrong!!!
Because 1024 Byte=1 KB and 1000 bit=1 kb so everything with 8 is wrong
right is 8*1024/1000=8,192 bzw. bei Mb und MB 8*1024^2/1000^2=8,388608
so right is:
Can we get a definitve answer as to which one of these is correct?
kb/s = kB/s multiplied by 8″
kB/s = kb/s divided by 8″
or
kb/s = kB/s * 8,192
kB/s = kb/s / 8,192
I really appreciated this advice. At first I was concerned by all of the virus reports, but I ran a scan. The scan came back negative so I took a chance. The patch and tweaks worked great and now my normal download speed of around 100kbs is up to around 180kbs.

Does anyone know what is the best download speed inorder to get highest upload speed? (i’m trying to increase my ratio w/ a website and i’m not having much luck.)
I have 200 in max half open on my computer buth on torrent is 43 i have there :D
F..k, that was a backdoor hacking tool virus, i scanned it with f-secure 2006!
Don’t install guys…
and remember… Don’t fuck with the WINDOWS folder!
For crying out loud, here are the FACTS:
The lvllord.de patch IS NOT A VIRUS. There is nothing malicious about it whatsoever. Anti-virus programs don’t like it because once your system is patched, worms can spread much faster than with only 10 max half-open connections.
Windows XP and SP1 are not limited to 10 half-open connections. This was introduced with SP2.
Only download the patch from http://www.lvllord.de because there are altered versions out there that DO include viruses and/or malware.

I am so confussed on how to set my upload and download speed on bittorrent!
First off how do i calculate my speed…. i mean is there a site that does this for you, is it in a manual i dont own?
Q.. How do you find out your maxium upload and download speed????

The website of your Internet provider should list your connection speed. For example, I use Shaw High-Speed Internet and at their site (http://www.shaw.ca/en-ca/ProductsServices/Internet/) it shows that my max download speed is 5Mb/s and my max upload speed is 512Kb/s.
If their website doesn’t show your speeds, you can call them to find out. But it’s not really that important to have the correct settings in your BitTorrent client. Just set it to the closest of what you think it might be.

I just got Bit Tornado and im wondering why my torrents download so slow..they download like at 0kb-1kb-2kb a second. 2kb if im lucky..whats tha deal? I have cablespeed internet too. Can someone help me out here. The seeds and leechers are both pretty high..
Hi this may be a stupid question but I need help!!
On my first torrent download I was getting a 64kb/s download but I went to make another download the day after and only got 2-3kb/s WHY??
Please help!!
You probably already mentioned how to to do this, but how would you encrypt the files on just the regular Bittorrent Client?
Best site in bleep! My thnx to webmasters.
Thanks for nice and actual info’ Be the Best!
Appreciate it men!
Hey Ernesto or others: I am experiencing drastic flucuating Byte rates within Azureus. I can not hold a steady rate, it constantly flucuates from ~120kB/s down to 0 kB/s. Typically, it will stay at 0 kB/s for 10-20 secs. then start to climb, hold for about 5 secs at 50 - 100 kB/s then gradually shoot back to 0, then repeat the cycle. Is this normal? If not, any suggestions? It is consistant with every download, regardless of seeds vs. leeches (although this matters!). I am using Azureus with a speakeasy.net tested Download speed of 8600 kbite = 1075 kByte/sec and an Upload speed of 529 kbite/sec = 66k Bytes/sec. I am on port 1720, and have followed all your recommended ratios. I have windows set to handle 100 connections. Thanks in advance and great work!
what if my univrsity dont allow bittorent (or any P2P prog) to be run? coz its like the p2p app has been blocked and the download will not start even when the seeders are plenty.. can any1 help me?
wow this certainly helped alot. very much appreciated
Great guide! But I got one question.
What about the “Global maximum number of connections:” setting in uTorrent?
nice artical. My download speed went from 5kbs to 150kbs after I did all of these settings. lmfao thanks
ey mates i tried all of the above steps to make my dl’s faster but it made it slower?!? did i do anything wrong? i used to be able to dl at around 50kB now im down to 1 please help

ok i need help. i think i set something wrong. my utorrent download speed is very sluggish. someone help.
my connection speed is 4000.
and my download rate is 420.
im not sure about how many peers i allow…
can someone help me figure out what im doing wrong?
every _bit_ is a value of 1 or 0.
every _byte_ is made of 8 bits, and thus can be 2^8=256 different numbers from 0 to 255.
learn programming :)
I’m using BitTorrent as client but I want to change to uTorrent. Do I have to wait untill all files in BitTorrent are downloaded before I can uninstall BitTorent and install uTorrent or will uTorrent keep downloading the files from BitTorent when I don’t have them for 100%?
Im currently using Shaw with bitcomet’s encryption system and it still is throttling my DL speeds. It won’t let me go any higher that 100kbps. mind u i’m on Shaw Extreme-I so i should be getting a lot more (up to 10mbps)
Any workaround with this?
sorry for being so thick but if i have a 7.9Mbs connection what settings do i need?
The article says nothing about max torrents queued or started.
nice article dude!
my DL speed jumped from 12,15,16…kb/s to 33kb/s!
and about the virus thing, it did not affect anything in my pc and did not detected it as a virus or a threath!
thanx!
thank you so much! my download speed was like down to 1Kb/s - 5Kb/s when i changed ISP , now its back to how was like with my old ISP , usually around 20+kb/s , sometimes 40+ .. not the greatest but ain’t complaining , i havent got the best connection speed..
Hi, i did the patch but it shows “Error in writing to file:%systemRoot%\system32\driver
\TCPIP.sys.original”.
How do I resolve this solution.
Hey man,
If I took all the half pennies at the banks created by exchange rate conversion and converted them to kb, how many kb would I have?
I have the same problem as matrix20xx. Can anyone help?
wow, Im only on step one, and WOW!
I’ve got vista and the tcp wont work on vista, I’ve even tried in safe mode as well. Is there a 4224 patch yet available for Vista? Help me out please, Thanks.
keep up the great work.
hey…when i try n run the patch…an erroe occurs n it doesnt run. what shud i do?
Hi
i have 1.2mb\s and did the patch thing and i did the tcp on bitlord and i still have very low speed like 4kb/s
it drives me crazy
please help!!!!!!
we should find a solution to improve our download speed rite?not to find which is rite,kb Kb 8 8*1024 or whatever….
Load of crap….. Don’t bother!
it isnt a load of crap unless you dont have xp installed the tweaker you need to play with but the patcher is not a virus and it does work just fine anyone who says it does not should shut off the computer (if the morons can find the button) and back away b4 they hurt themselves or the computer
LEARN TO USE THE THING YOUR TYPING ON ffs
why is that wheneevr i download something and if it reaches to 72% - 75%.. its downloading speed drops from 31kB/s to 0.3kB/s - 1.2kB/s..
wahhh..
could somebody help me how can i fix this..
Crazy page
really works guys
if this page was a girl i would have slept with it
The patch once applied cannot be uninstalled. it stays. i have tried it a lots of time, and could not successfuly uninstall the patch. My upload speeds go crazy, and Slows down every thing else, and after applying the patch i cannot control the upload speeds through a torrent client. I just have to Reinstall XP to undo the patch.
could someone please help me? i ran the patch and now my internet browser cannot find the srever, i can connect to the internet but cant access it
When I downloaded this it asked to restart the computer and now i have like no seeds on my torrents and computer is lagging real bad. any help?
I was wondering if you can help me out to do the same with Azureus. I am having trouble with that??
before i download a torrent, how can i check if my Creative Zen music player can support it.i have downloaded mant things only for it to say that my player does not support it. its very fustrating.Also why half way through a download does the green download arrow turn to red ?
thanx OTHELLO
This website is DEAD ON CORRECT for those of you who are just learning. Just re read it and you will be good to go. Also you have to remember that these settings are going to work differently for everyone so just tweak them a bit. I learned myself from a post just like this about a year an a half ago and when I started on my own I was downloading at about 28 to 47 TOPS! After following these same instructions I downloaded a 4GB dvd iso in under an hour at 320 - 500 TOPS!
But now I am in need of help again. Is there ANYONE that has heard anything about being able to have more connections in Vista? Because if not I am going to SERIOUSLY be BUMMED…lol Vista is sooo pretty..lol but I will go back to XP because I NEED my TORRENTS!
HELP!
Well, read the post and found it a little helpful but, not much. Tried out the patch and it didn’t do anything for my dl ratio but then again it wasn’t bad to begin with but when it comes to the download ratio form web-pages it worked wonders. Getting the things faster is always nice when you download big files.
“patch is a virus”.. F.U.A… it is no virus and it’s easy to remove the files created by it… use UnLocker… it’s free and can be found on the net.
Computers will never take the place of books. You can’t stand on a floppy disk to reach a high shelf.
This improved my torrent download speed by x20! This helped me alot thanks!
With Bit Comet, you can set the tcp/ip thing without using that patch. It’s in Bit Comet version 0.84.
The patch is also not a virus, tho my AV also thought it was when it scanned it. The thing is, my XP SP2 had 50 open - and in the DOS screen that the patch initiated, it asked if I wanted to change 50 to 10. I had previously applied that patch. Normally, a windows update should reverse the setting back, but mine did not do this. I had 50.
I also have a question that someone else asked.
Max connections and
Global max connections
I see no option to change the number of peers. Please EMAIL ME if you have Bit Comet directions for this, if you can see the email above.
Thanks
the patch is not a virus and it works well for me,i have update to 50 TCP connection and now my utorrent is DL-ing at a avg 70-80 KB/s
thank you :)
I have to tell you all. This works! i was getting downloads of 1 -18 at the most and the 18 was for only a split second. now i’m at 37 !!

Moron. What is 1 kB/s multiplied by 8? 8kB/s. What is 1kb/s multiplied by 8? 1kB/s. What you said does not equal what you wrote as a formula. The correct formula is:
1kb/s = 1kB/s divided by 8
1kB/s = 1kb/s multiplied by 8
Still don’t believe me? Use simple algebra to make both sides equal. If you’re still having trouble, consider the above table in this format:
8kb/s = 1kB/s
(1/8)kB/s = 1kb/s
This whole thing was fine in the article, quit being ‘tards.
Ok, I changed all the settings detailed. Did a reboot. But now my torrents are downloading at about 10kb/s and before the changes they were about 100kb/s. The swarm average speed is 390kb/s. What’s going on?! I tried changing the settings back but still only 10kb/s second. How annoying.
great article, its definantly increased my speeds. patcher worked as it should. thanks
Help me please, i downloaded a prison break torrent on Bit Comet but i cant find it when i browse the destination directory, please someone tell me whats the problem, it took over 3 hours to download and has a green circile beside it! Whats the problem please help!
i love arguments on the internet, makes me feel all warm and fuzzy inside. and probably outside too. har
[quote comment="6456"]Nice article ..except for this slight mistake “kb/s = kB/s divided by 8″ … It should have been :
“kb/s = kB/s multiplied by 8″ or
“kB/s = kb/s divided by 8″[/quote]
Big friggin deal.
to those who were sayin that the patch was a virus: u guys dont know shit..so better keep ur ideas to urselves.. i hate amateurs
PLease can anyone tell me whats my problem here. Im using bit comet and im always trying to increase its speed. It used to download up to the speed of 30kb per sec. I dont know why but suddenly the speed drops to zero and never rises. Anyone who can help me please e mail me at arvin_1108@hotmail.com
To those having problems with Windows either being slow or requiring patches to speed up BitTorrent:
Just use GNU/Linux or *BSD, and that problem will go away. Their TCP/IP stacks don’t have artificial limitations imposed on them, and they work *GREAT*. For Windows users, I’d recommend Kubuntu.
For Vista, I found an article which mentions to set TCP/IP auto tuning to Highly Restricted instead of disabling it completely.

audio torrents b 4 reading these tips and was getting download speeds of 3 or 4 Kbs. Now I get 400plus Kbs.

limited uploads to 400kbs
max connections to 200
maxed peers per torrent to 100
upload slots to 10

Thanks a lot. just went from 6kB/sec to 60kB sec :)
When I connect to the internet it shows that I am connected at 100Mbps.
But, when I download a Torrent or anything else the download speeed is hardly 15 - 20 KB/s.
Could someone please tell me why this happens
I love you, dude! That patch and your tips put me up from 6 kB/s to about 75-80 kB/s. Thank you very much!
Patch contains a virus. It does max your connections but I lost my graphic driver after installing it (block at 640*480 or 800*600) if it’s happens just re-install your graphic drivers. :(
First off, let me explain a couple things to the Newbie users out there. The patch contained within this page, is NOT a virus. The patch DOES NOT interfere with ANY other settings, than connection information. Meaning, that there is NO WAY in hell it could ‘crash’ your graphics card. That’s like saying “I put a floppy in my computer, and the monitor busted into flames…”. Also, TCPIP.SYS is the only file that is affected AFTER the patch is complete (I think). You may notice TEMP directories and other anomalies, as you would with ANY program, especially using a decompression agent (If it does). The Patch WILL NOT crash ANYTHING, unless something happens in the middle of altering the file, such as a power failure. Then the blame lies in the failure, not in the patch. In any case, you only need re-run the application, to fix your internet (If it will not work), and finish the job. On WinXP you may notice a file dialog box, that says you need to insert your WinXP CD to replace and important file that has been altered. Hit the ‘Cancel’ button, because this is just an effect of the program altering sensitive settings within a file deemed important by XP. Also, DO NOT use BitLord, BitSpirit, or other generics. Use uTorrent, BitComet, or Azureus. The rest do NOT support encryption, and are cheap copies. I have had read many reports of encryption increasing speeds by up to 300%. BitLord, BitSpirit, and etc, do NOT support encryption. Whereas uTorrent, BitComet, and Azureus DO. Let me make this FINAL and CLEAR. THE PATCH IS NOT A TROJEN, WORM, VIRUS, BACKDOOR, or ANYTHING OTHER THAN A GOOD, PERFECTLY WORKING, PATCH. All those newbie users out there, who see that Virus warning and do not realize that everyone here is trying to tell you that AV programs are so secure about code anymore, they are NOT always right. I only hope to educate. Thank you all for reading this… Happy Torrenting! BinaryBrother

Great tips, I worked before with a max 20kB/s upload rate before and unlimited download rate, also a 5000 max peer connections, 8 max upload connections and 1000 max overall connections.
After using your tips my download speed deteriorated dramatically.
The only thing that I benefited from this article was a bit of knowledge and the great tip of patching the max half-open connection limit (which by the way increased my download speed by up to 4x)!!!
Keep up the great articles which should I mention; there are three on this topic which are nearly identical::
http://torrentfreak.com/speed-up-your-torrents/
http://torrentfreak.com/speed-up-your-torrents/
Oh and I found another article on the web again almost-nearly identical, not sure if this site copied from them or they copied from you, but this site sure does include more in-depth information. Here’s the link, just thought you might want to take a look:
http://www.johntp.com/2006/04/19/how-to-increase-download-speeds-of-utorrent/
Oh and I should add that the patch IS NOT a virus, my BitDefender Antivirus Plus v10 detected it as one, only meerly because it deals with advanced settings inside windows which are fragile. And since my Antivirus is so god-damn protective of my system ^.^ I had to set default settings on the anti-virus so it wouldn’t scan incoming http:// traffic, download the patch, disconnect my internet (so I wouldn’t be vulnerable to hackers), and then exit bitdefender, and patch, otherwise the anti-virus program would scan the patch right when I clicked on it, quarantine it then remove it.
Great tips and to others with the same anti-virus program as me I hope this helped!!!
Aww do I loooooooove virustotal.com, half of he results said that this WAS a virus and some even said it was a hacktool! I deleted the file without even opening it. HA!
hi, i’m just using bittorent, the program i downloaded from the bittorent website
where can I choose on the program how to control my max upload speed? all i see is “file, view, torrent, help”
your help will be greatly appreciated thanks!
i did all of this fucking thinks but nothing change my utorrent speed. still i have got 12kb/sec.i m really pissed.
this guide is pretty good , thanks a lot .
Great guide!
Biggest difference for me was changing the cap on my upload speeds. I went from about 10 to 100kb/s.
the only thing I didnt do was the patch. I can live with slow dl speeds, what I can’t live with is reinstalling windows and losing all of my files.
i done everything that was said to be done and my download still dosn’t start can anyone help
this is a great article alot of help towards sorting out these damn slownesses lol
but i wudnt use the hacking tools
listen to me, dont mess with windows files or ya computer reli,
i used to be the master,
at making my computer faster,
but then i fooled around modding files with programs that you cant reli still trust regardless of what ppl have been saying. so den i became…
the master,
of diaster!!!
lol but you get what am saying so take it easy
how can i uninstall this patch??!?? pleeeaase! answer me!!
@Leigh if you would have payed attention with the instal and READ everything that it was showing you you would know how to change it back by patch OR manually.. people are to lazy to read these days and come with HELPME!!!#$!@ posts
nice article…usefull…didnt download the patch tho..
i manually modified the settings
and for anyone who’s wondering, this patch dosent work for vista. if ur using vista and want an effecient way to speed up yer torrent download, then its simple, get a faster connection. !
ALL ISP’S THAT LIMIT BT’S CONNETION ARE GAY. THAT’S THE REALITY..
Wow I’ve never seen so many ignorant uninformed people in my life. How stupid could one be? First of all its not a virus all it does is patch your tcpip.sys if you were to do this manually you would have to open tcpip.sys in a hex editor and byte hack it. If you are so worried about a couple of blatant false positives use XP-Antispy which includes an option to set max connection limits just like the patcher does.
All the half-open connection does is set how many different peers it tries to connect to at the same time decreasing the startup speed of your torrent nothing else.
The article contains clear instructions with pictures anyone should be able to pick it up and do it. I also saw somebody ask why it says when they connect online they have a 100Mpbs connection but only download at 4Kb…WOW just WOW, that’s the speed available on your LAN(LOCAL AREA NETWORK) not your actual internet speeds. Use speedtest.net if you want to know your actual speeds.
The settings listed in the article will affect everyone differently as there are hundreds if not thousands of factors to consider, like ISP, connection type, NIC, OS and OS configuration, current usage, network congestion, torrent health, seeds/peers etc etc etc the list goes on and on…hope this provides at LEAST a little insight
Shit type from my previous post
“All the half-open connection does is set how many different peers it tries to connect to at the same time decreasing the startup speed of your torrent nothing else.”
should really be
decreasing the startup TIME of your torrent, sorry bout that
This was really helpfull!
Thanks a lot!
hi,
i was downloadin a movie but had to uninsatll the torrent due to some reason…
now how to add the torrent agian n start downloa from where it left…..
that patch program is a virus. it deleted my system volume information -.-
This patch is destructive to a virus called Win32/XP or Win32/Vista. It wipes it out then downloads an Operating System such a Ubuntu. It installs that.
This is very useful to me
thanks i will send it to
my friends also!
This info is really great. It got my download speeds from around 67 kB/s to almost 200 kB/s Thanks for putting all of this together.
Thanks a ton man. I had known of torrents for a long time and had never gotten around to using one because:
1. Nothing ever seemed to download for me and it all seemed confusing.
2. Limewire, Kazaa, etc. always had what I needed, regardless of the fact that I spent more time fighting viruses when I used them than having fun.
Thanks a ton man, you really got me moving now and I actually understand all of this now.
I followed everything and it worked GREAT… except that TCP optimizer.. just made everything slow again… how can i undo what it did?
I love you. you tripled my speeds. But i still see peers d/ling at 300-500 kBps… Y?
after runiing XP antispy and patching with evid4226 I lost my network and now xp cant creat a network with the wizard, system restore will not allow me to go back to an earlyer restore point as well. but my torrents are downloading through Utorrent much fast now. We may have to buy a wireless printer now for lappy to be able to print :( any ideas?
Hello I must say great info here I just have one question.
I use Bitcomet 0.96 . How do I go about Changeing the default port? I know my isp has ports for p2p all most crushed closed (know one of there people). I thank you for the time you have taken to give us this info, and hope I get a fast reply.
Drgon
thank you for a great tips! it really work`s!
Awesome article. I learned a few things from reading it.
<3
great article thats sure thing however best solution to dload torrents faster is simply be a member of a good private tracker where ppl take care of the ratio they have and rather seed than just lech…

I’m not particularly fond of jews.
I read the whole thing. I will try and see what happens. Thank you to all those of you who know about the subject and want to positively help–especially those who have a benign spirit.
I followed the instructions partically and noticed a jump from around 70kB/s to 150kB/s. I later finished the remainder of instructions and utorrent required me to restart the program.
It restarted with slower download speeds (30kB/s or so) and higher upload speeds (80kB/s or so).
15 minutes in and the speeds started changing.
I am now downloading varying between 200kB/s and 300kB/s and uploading at 50kB/s.
Those of you who are complaining about speeds… give it time.
I’d still like to sneak closer to my prime 400kB/s.
Every so often I’ll download a file at + 800kB/s.. or more usually multiple files totalling around 800kB/s.
Any ideas how to get THESE speeds from utorrent?
tried these suggestions this evening and they’re great. consistent download speed and my uploads are 1.5 times faster win/win thanks!
Great Article, helped me alot!
About the virus, I haven’t experienced any virus effect and I am running MacaFee and AVG also, before you run the patch I suggest you backup the C:/WINDOWS/System32/Drives/tcpip.sys
file. I always make backups of eevery file that has been edited in the Windows Folder.
do these TIP also apply to Windows Vista ?
I’d prefer reading in my native language, because my knowledge of your languange is no so well. But it was interesting!
Thanks for creating this, Ernest. I consider the tips listed on this site to be quite interesting and beneficial.
However, I’d love to download that TCP thing but I’m honestly afraid that it will harm my computer in some way. A few people have shunned it, while others have agreed that it is a healthy file.
I guess what I’m really trying to say, Ernest, is…
Can I trust you, brother?
After initially approving it I am taking back my comments on this patch.
I have observed it’s behaviour. Although it DOES change the max no of open connections in TCPIP.sys, it’s a virus.
Bit Defender kept blocking it from executing itself several times even hours after I applied the patch.
In just downliading a torrent, but i have upload speed too, something is uploading from my pc. i wanna know what is going ot from
