uTorrent Gains Popularity, Azureus Loses Ground

Written by Ernesto on December 16, 2007 

With an install rate of more than 5% on Windows PCs worldwide, uTorrent is now by far the most popular BitTorrent client. Azureus, the most installed BitTorrent application of last year fell back to the third place.

uTorrent is Gaining Popularity, Azureus DecliningThe graph on the right (click to enlarge) is based on data published by Digital Music News based on reports from PC Pitstop, a company that gathers data by “inspecting” the computers of users that try their free online virus / spyware scanners. The data used in this report are collected from Windows registry and table entries of over a million PC’s.

The percentages reflect the percentage of PCs that has these applications installed. September last year Azureus was installed on more than 3% of all PCs but their install rate has declined by more than 30% this year, while uTorrent’s install rate nearly tripled.

In the table below we have listed the 5 most installed BitTorrent applications. It is interesting to not that Azureus moved from the first to the third spot over the past year. The BitTorrent mainline client is now runner up. This means that BitTorrent Inc. now owns the two most popular BitTorrent clients.

The percentages in the table indicate the install base of the most popular BitTorrent clients:

Rank Application Installed on % Desktops
1. uTorrent 5.56%
2. BitTorrent (a.k.a. mainline) 2.28%
3. Azureus 2.11%
4. Bitcomet 1.89%
5. Bitlord 1.27%

From the data where the report is based on we further learn that Limewire’s popularity is slowly declining. However, with an install base of almost 18% it is still the P2P application that is installed on most desktop computers. Unfortunately Digital Music News has trouble interpreting their own data, they claim in their press release that it is 36.4%, but that is the market share compared to other P2P clients (shame on you!).

Apart from this tiny mistake, there are a few more concerns about the usability of the data. For example, install rates do not equal usage. The fact that someone installed a P2P client does not mean that they actually use it. So the report can’t say much about the popularity of a filesharing network or application. Secondly, it could be that Azureus and BitTorrent Mainline are installed on almost an equal number of PCs, but that the BitTorrent mainline client is hardly ever used. For instance, novices may start with the mainline client, but move on to better BitTorrent clients later on. Lastly, the report is based on a sample of people who voluntarily did an online spyware scan, something to think about.

Perhaps an even more important comment on the data collection for this report, uTorrent doesn’t necessarily use the Windows registry. So the real install rate for uTorrent might be even higher. Also, Azureus is a true multi-platform client, whilst this test is only for windows based systems.

In summing up we think it is (despite all the flaws) safe to say that uTorrent is becoming more popular while Azureus is losing ground. Whether this is due to negative factors affecting Azureus (such as the rebranding to Vuze, Java or the heavy use of resources), or positive factors around the mainline and µTorrent clients (such as the small install size, and low system requirements) it certainly shows a slide for Azureus.

I am currentoy using uTorrent, but I know that all the power/experienced users will switch to Azureus…if only it didn’t hog my system so much!!!

77 Dec 17, 2007 at 16:18 by TechCF

I also use uTorrent, even though it isn’t available native on my platform (Linux 64bit). It is the greatest bittorrent client for my use.

I’ve done speed testing with uTorrent and Azureus. Azureus downloads torrents faster, hands down. I have no idea why this is the case. But despite the fact that uTorrent *is* nicer to use, I have now removed it from my system because it’s just doesn’t get me the content as quickly as Azureus. I was very surprised to see that no-one else commented on that here.

[quote comment="240785"] Being as I deal with people using bittorent on a daily basis in a support role, I deal with far more people having problems with utorrent than Azureus, perhaps Azureus users are slightly more adept than utorrent with the main problems stemming from Azureus being lack of knowledge on the users part. Most of which cant even figure out how to set it up. For those people then the simpler utorrent is more at their level of understanding. One thing that lets utorrent down significantly is its complete lack of peer banning. As an example, U didnt have a torrent client installed at one point and rather than have to set up Az for a single download I opted for utorrent. An hour later and 60 hash fails I still had sod all. So I went and grabbed Azureus, set it up and completed the download in 8 minutes, with 3 hash fails and 6 peers banned for sending bad data. For that reason alone utorrent will never be as good as Azureus.[/quote]

Like you I do a lot fo torrent support. You’ll find me right now (amongst other places) in the Utorrent support channel AND the Az channel. I personally have been following and supporting µTorrent for 2 years - I was the one that got Ludde and bluetack talking about when they added utorrent.com to the blocklist, over that retspan misunderstanding.

I am also quite well known to the Az des - myself and gouss has endless talks about Az, and especially about az’s features and system usage. I even have a printout somewhere of him telling me “Az really needs 2ghz processor and 512Mb of ram - back in 2004. That is min specs for games NOW, 3 1/2 years on, was WAY above reccomended specs then. Bittorenting is nothing complex, it’s a simple data transfer protocol, with error checking. There is no way, NO WAY, it should take so much on system resources.

By the way, you kind of shoot your credability to hell when you talk about Ut’s lack of peer banning. It most certainly does ban on hash errors, and has done for a long time. In fact, 18months ago, when, I think it was Mediasentry, were attacking torrents with clients sending out garbage, it was Az that was choking, not the others.

The only sort of peer banning µt doesn’t have, is manual, and the reason is simple, and understandable - ‘know-it-alls’ that ban, because they think they know better. As for smarter users - I doubt it; else there wouldn’t be comments like this (from earlier on today) “what does forced seeding mean? how is it different from regular seeding? in your opinion is it better to force seeding, or to regular seeding. (I want to help my ratio go up)” Theres a hundred more I’ve collected just this week, of questions answered in FAQs.

2600 - in short, attitudes like yours are what has made the software industry the cesspool it generally is now.

I bet these numbers include warcraft’s torrent downloader as part of Bittorrent, Inc’s numbers.

I ditched Azureus once it stopped being a clean Bittorrent client and became a huge bloated mess plastered with videos and various other junk.

Its obvious that Azureus was cut-n-pasted into the Vuze system without much thought for integration. What were they thinking?

uTorrent is a far better designed and laid out piece of software … but I didn’t know about it’s change of hands. v1.6 here I come …

84 Dec 17, 2007 at 20:35 by kuratkull

Oh the horribly cumbersome Java Virtual Machine!
I’m happy that uTorrent is taking over.
Now if they’d only support Linux systems :)

85 Dec 17, 2007 at 20:42 by LqR

Too bad a non-free client is replacing a free one. I agree Azureus is one of the most insanely resource-hogging applications I’ve ever seen and I loathe Java, but at least it’s free software, and I have heard it can be run on free VMs as well. µTorrent is not only non-free for no good reason, but it also requires a non-free and quite worthless operating system to run (I know it works under WINE — although not very well). And its developer seems like a shady person with a “shut up, I’m the developer here” attitude.

86 Dec 17, 2007 at 20:50 by kuratkull

It’s not free(as in beer or freedom)??
I never knew that(well, I haven’t really checked into it, because I’m not using the Win32 platform)…
But since 99,99% of uTorrent users are Windozers(the 0.01% is for WINErs), then I don’t have a hard time understanding the not-caring attitude towards the license of uT.
sad…
And Azureus with sun java_vm or without sun java_vm, it’s still java, and it’s still bloated with features not used by most peers.

[quote comment="240768"]uTorrent beats Azureus hands down - the only reason I’m using Azureus is because there isn’t a Linux version of uTorrent. If there was, I would switch right away. But KTorrent has been getting better, so I might have to switch to that. There’s no doubt that Azureus/Java hogs RAM and CPU cycles,

something that must be pretty detrimental to its popularity.[/quote]
i use utorrent on linux: wine is the answer.

weird, because to me it’s the other way around. utorrent gets the content much faster than azureus. and i’ve made comparisons 2-3 times.

Umm… not necessarily. The recent MediaSentry e-mail leak pointed out that they were focused on damaging uTorrent rather than Azureus.

And Azureus’s hash banning system is better than uTorrent’s - check the changelog for uTorrent’s 1.8 alpha builds.

90 Dec 17, 2007 at 23:56 by omar

I used to use Azureus, but now I use uTorrent. As much as I love Azureus, it eats up too much resources. uTorrent does almost everything that Azureus does minus the resource eating. Azureus is a great program, but in my opinion, uTorrent is slightly better.

Amen! and a slap on the wrist to Ernesto for this article. The title is very misleading. It should be “uTorrent is more popular amongst clueless noobs” What technically-literate people use is another matter.[/quote]

But they are a much smaller sample size of the total population, and therefore statistically much less relevant. :)

one thing remains truthful.
bitcomit and bitlord rly do suck some rhino’s but.

95 Dec 18, 2007 at 03:42 by SevereTwitch

Dunno.

Azureus seems to run nicely enough on my *nix box, provides an effective and functional web UI (handy, since we use a shared install on my LAN), the RPC support makes it possible to check torrent status from my Mac’s Dashboard, and the RSS plugin support allows me to watch the TV shows I want with effortless time shifting (I work odd hours).

I neglect to see the downside.

96 Dec 18, 2007 at 07:44 by Weep for the Dorm Students

Well, I haven’t tried uTorrent, but Azureus would only get about 40kBs max; usually more like 20-25 kBs.

Just switched over to bitComet, and wow! I’m getting ~170 kBs.

Limewire can get about 400 kBs, but only when downing multiple files; probably 130 kBs max / file.

I do know that the school here throttles/brutally throttles all p2p traffic whenever they can get away with it.

I also know that we “technically” (speedtest) have

I don’t know if the reason bitComet is so much faster than Azureus is because ‘Comet is a bit of a “bully” whereas normal clients/Azureus are , well, downright oppressive about maintaining a fair ratio;
or if perhaps ‘Comet packets are less detectable/easy to filter for whatever equipment and software this school’s IT dept uses;
or something else.

But hot dang, imagine whatever your current download speed is, suddenly getting multiplied by about 8, just because you switched clients; weee-haaah!!!

PS - Thanks to school, I can’t believe anyone in the world, let alone North America, can download at rates over 500 kB/s :(

Personally, I like a client with as much power (hard customizability, as opposed to “skins”:) as possible.
That goes in Azureus’ favor.

Also, if my client were hogging the system (+35% CPU, +35% RAM), I would ditch it for a better one. But Azureus uses ~2% CPU and ~5% RAM on a 3+ year old laptop; I’d say that’s within reason; again,
That goes in Azureus’ favor.

But Azureus is now owned by whoever does Vuze; and vuze doesn’t look good:

“It will also sell content protected by digital rights management. The company claims to have “distribution deals with 12 television, film and media companies”. On (date), the BBC announced that hundreds of episodes of its programs will be made available through Vuze…However, the Vuze-platform is not GPL-licensed and you can not install Azureus using the latest installer from the Azureus SourceForge page without first accepting the Vuze-license .”
Wikipedia, on Vuze

Not pretty; looks like, however “bloated” [not in my experience] it may be, azureus has fallen to major corporate interests.
NOT in Azureus’ favor.

At the same time, uTorrent is owned by BitTorrent Incorporated, which has also fallen to major corporate interests.[and is not under the GPL].

My conclusion, switch to open-source clients! Check out BitComet; they may have broken some formalities, but from what I’ve heard, they’re a pretty good one.
