Over the last year Vuze’s BitTorrent client has evolved into an all-in-one download solution. With built in search, DVD-burning capabilities and device integration the Vuze team has set itself aside from other popular BitTorrent clients.

Vuze’s device integration with iTunes, Xbox 360, Playstation 3, PSP and TiVo has been one of the most appreciated functions among users. Nearly 5 million users have been dragging and dropping videos to their devices, totaling well over 100 million videos.

With the release of Vuze 4.5 that was announced today, users of Android devices now also have the option to automatically transcode, transfer, and playback downloaded files. Several models including the HTC Evo, HTC Hero, HTC Incredible, HTC Magic, Motorola Droid, Motorola Droid X and Samsung Vibrant are already fully supported, and more will be added upon request.

Aside from Android integration, the Vuze team has been focusing on how to improve download speeds for its users. To tackle some of the most common speed constraints the latest Vuze release now includes a thorough speed test and optimizer to ensure that users get the most out of the client.

“We implemented the speed test to maintain power users’ ability to control their own settings – all manual controls still exist – while addressing the fact that a large number of users request additional help in optimizing their settings. Based on initial testing, many people should see significant increases in download speeds after running the speed test,” Vuze’s Director of Marketing Chris Thun told TorrentFreak.

The basic speed test uses MLab‘s Network Diagnostic Test to quickly test users upload/download capacity the first time they launch the latest version of Vuze. The client then uses the results of the speed test to adjust the following Vuze settings:

• Upload rate limit (80% of the measured limit)
• Maximum active torrents (seeding+downloading)
• Maximum downloading torrents
• Maximum upload slots per torrent
• Maximum peer connections per torrent (when downloading and when seeding)
• Maximum global peer connections

Via the Vuze Help Menu, users can run additional speed tests later. If the first test detects a reasonably high upload rate it will automatically add a follow-on MLab tool. This tool checks for ISP traffic shaping by prolonging the test for a couple of extra minutes, so it is able to detect the speed trend beyond the short-term burst at the beginning of a connection.

If traffic shaping occurs, Vuze will adjust the settings to ensure that they are properly updated for the best download speeds. This usually means that if the long-term uploads speed is significantly lower than the initial test, the setting will be optimized accordingly.

Vuze 4.5 is available for download at the Vuze website. The full changelog with new features, changes and the latest bugfixes is available on SourceForge.

The BitTorrent client has added a new feature that integrates Vuze with several media devices. It allows users to automatically convert and transfer downloaded videos to iTunes, and stream the files to the Xbox 360 and PS3.

“With today’s release, we’re unlocking HD content and giving it wings to get from the computer to the other screens in our lives: TV and Mobile,” Vuze CEO Gilles BianRosa told TorrentFreak. “We think this is a big deal because a large majority of our users actually have these devices at home. Also, consumers want to control and own their content, an ‘Open Home Theater’, if you will.”

Vuze currently supports Apple devices including the iPhone and the iPod. The PS3 and Xbox 360 are the two gaming consoles that integrate with Vuze as well. More devices may be added in the future but no decisions have yet been made on which ones, TorrentFreak was told. In a recent poll, most Vuze users indicated that iPhone/iPod support was most wanted.

Once device support is turned on in Vuze, users can drag and drop downloaded video onto their device of choice. Vuze will then convert the video into the appropriate format and add it to the device’s library.

For iTunes, Vuze will import the video into your iTunes library so it can be transferred to your iPhone, iPod or Apple TV. For the PS3 and Xbox 360, Vuze will stream the videos from your PC or Mac directly to your game console.

The device support is a great feature for users who want to have an easy all-in-one solution that not only downloads video, but also makes it ready to play on other devices. Although Vuze has been focusing mainly on video lately, the client can still download other content as well.

It is good to see that Vuze is using the feedback from its users to improve their client, although it is impossible to please everyone and some may still prefer a more lightweight client. That said, the Vuze all-in-one solution will especially appeal to novice BitTorrent users, but even for the most die-hard users the new features will make a great addition.

The graph clearly shows that Azureus was the most searched for client until the beginning of 2007, followed by BitComet. From then on, uTorrent took over and it continued to grow while BitComet and Azureus searches slowly decreased. Search statistics are of course only an indirect measure of the popularity of a BitTorrent client, but the graphs seem to follow the same pattern as actual usage statistics which we have reported before.

Worldwide

Another measure that is worth looking into is the geographical distribution of the searches. It is interesting to see how popular BitComet is in Asia. Currently, it is (based on searches) the preferred client in China, Taiwan, Thailand, Malaysia and Hong Kong. However, uTorrent is most often searched for in most countries, especially in Moldova. Azureus, on the other hand, is a popular search term in Greece.

US

If we take a closer look at the US (you can do this for any country), we see that pretty much every BitTorrent client is popular in California. The graph shows that most uTorrent searches (relatively) come from Kentucky and California, Milpitas in particular. Azureus seems to be quite popular in Ohio, specifically in Salt Lake City. BitComet is the least searched for client of the three, but gets most search traffic from New York and California again, Monterey Park on this occasion.

Overall I would say that based on other statistics, the search data is a pretty close match to the actual BitTorrent client preferences. Google’s insights on the regional differences certainly have something to add to what we already know, but keep in mind that they are only search statistics. Most of all, it’s a fun tool to play around with on a Sunday afternoon when there’s not much news to go around.

Things changed in 2006 when Azureus launched the content distribution platform it called ‘Vuze’ (aka Zudeo), backed up by a total of $34 million venture capital. For a while, they kept releasing a no-Vuze version of Azureus (when Vuze/Zudeo was in Beta), but Vuze CEO, Gilles BianRosa told TorrentFreak that this only caused confusion among their users.

“We started to change our name from Azureus to Vuze over a year ago, but we did not make the change in a clear or consistent manner,” Gilles said. “This has caused a great deal of confusion amongst our users. We want to rectify this situation by changing our name to Vuze consistently.”

“Whilst we recognize the strength of the Azureus name and the frog, it is only associated with our original BitTorrent application. As we move towards creating an all-in-one application for finding, playing and sharing great content, that goes beyond the realm of just a BitTorrent client, we wanted to change our name to reflect that, but bring with us the frog who is such a part of our heritage,” Gilles added.

Today, Vuze comes with a brand new release of their client (v3.1), introducing several new features. One of the most drastic changes is the new social layer that has been added to the client. Vuze users are now able to add friends, share torrents with friends, and give friends a speed boost when you are downloading the same torrent.

The new client also includes a meta-search engine that allows you to search across several popular BitTorrent sites, in addition to content from Vuze.com. The search functionality is completely customizable, so you can add you personal favorite if it’s not already included.

Unfortunately, there will not be a Vuze client available without the Vuze platform integrated. Gilles told TorrentFreak: “We are focusing our efforts on delivering against our vision of creating an all-in-one application that enables users to find, download, play and share in one streamlined application.”

“We have started on a path of creating an all-in-one application that enables users to find, play and share torrents. In particular, we believe that by enabling users to share content and bandwidth through the “Friends” feature we are adding a completely new dimension to peer-to-peer – a new social dimension, or what we call ‘social P2P’,” Gilles said.

Azureus is no more, the name change is permanent. On the one hand this is a step forward, as the new interface and functionality will appeal to new users. However, it has also caused quite a heated debate among both developers and users who were happy with the classic UI. Although, it’s a bit hidden, the original interface still remains accessible with the UI switcher. Time will tell if it is the right move.

A few months we already reported that uTorrent overtook Azureus’ position as the most installed BitTorrent application, and this trend continues. LimeWire’s popularity on the other hand is declining worldwide. Nonetheless, it is still by far the most installed filesharing application.

LimeWire going down, uTorrent on the rise

From December 2006 to December 2007 LimeWire lost approximately 25% of its user base. By the end of 2007, 17% of all PCs in the United States had LimeWire installed, compared to 23.3% last year. Similar drops occurred in Europe, Latin America, and the rest of the world. The most loyal LimeWire users come from Australia, where the install rate is 27%, only a slight decrease compared to the 30.4% in 2006.

The uTorrent user base on the other hand is rapidly growing. uTorrent installs more than doubled in nearly every part of the world in the last 12 months. The BitTorrent client is most popular in Europe (11.6%), as can be seen from the graph below.

As a result of uTorrent’s growth, other BitTorrent clients such as Azureus and BitComet are going downhill. Azureus and BitComet now have an average install rate of 1.4% and 1.7% respectively.

Regional Differences

The regional differences in popularity of p2p applications are also worth mentioning. The data show that uTorrent is far more popular in Europe (11.6%) than in the United States (5.1%). Limewire on the other hand is well-liked among Aussies (27.0%) and Canadians (27.2%), but has less followers in Latin America.

Emule is still very popular in Latin America, where 16% of the PCs have the application installed compared to only 1% in the United States and 3% in Europe.

Home vs. Business PCs

Unsurprisingly, P2P applications are more frequently installed on home computers versus PCs at the workplace. Nevertheless, almost one out of five PCs at work (18%) have at least one P2P application installed. For home computer this is little over 1 in three (36%)

P2P Market share 2008

We also compiled a pie chart of the market share of the different P2P applications as of January 1st 2008. Please note that the data is a bit skewed since most of the data comes from participants who were based in the United States. LimeWire is without a doubt the winner here.

Finally, we want to make it clear though that install rates do not equal usage. The fact that someone installed a P2P client does not mean that they actually use it.

Based on the amount of traffic that is generated by each P2P application, uTorrent would be the absolute winner.

A few months ago Azureus petitioned the FCC, which led to a FCC hearing in February. One of the complaints from the commission was that there is little data available on the scope of BitTorrent throttling, a gap Azureus now tries to fill by collecting data on the prevalence of TCP-resets among ISPs worldwide.

Last month Azureus published a plugin through which users can help distinguishing the good from the bad ISPs, and today we have a preview of some early findings. A massive 1,000,000 hours of data from over 8000 users has been collected over the past few weeks. The preliminary results again confirm that Comcast continues to use TCP-resets to manage BitTorrent traffic on their network, but they are not alone.

The rest of the Vuze/Azureus report (pdf) includes the median reset rates for hundreds of other ISPs

TCP resets seem to be more common for American ISPs, and Comcast leads the bunch. The Azureus team has sent a letter to Cablevision, Cogeco, BellSouth and AOL, where they request that the companies are open about their BitTorrent throttling practices. Thus far, the ISPs have not responded to the letters.

At the bottom of the list we see the good ISPs, mostly from Europe. There are other ways to throttle BitTorrent traffic, besides using TCP-resets, a list of ISPs who are known to limit BitTorrent traffic is available on the Azureus Wiki.

It has to be noted that the data gathering techniques Vuze uses are far from optimal. The plugin detects all TCP resets on a connection and doesn’t make a distinction between BitTorrent and other traffic, and there is no control group.

The Azureus/Vuze team will continue to collect data, and stated:

“We believe that there is sufficient data to suggest that network management practices that ‘throttle’ Internet traffic are widespread. At a minimum, more investigation is required to determine whether these resets are happening in the ordinary course of business or whether they represent the kind of throttling practices which target specific applications and/or protocols, harming the consumer experience and stifling innovation.”

The preliminary results presented here do indeed indicate that Comcast is not the only ISP that uses TCP resets to slow down BitTorrent traffic. People are encouraged to continue using the plugin so more robust data can be presented in the near future.

“We at Vuze (Azureus) decided there was something important you can do to help elevate the debate,” says Jay Monahan, General Counsel at Azureus. “We created a simple software “plug-in” that works with your Vuze (Azureus) application to gather information about potential interference with your Internet traffic.”

The main purpose of the plugin is to gather factual data on which ISPs are throttling with BitTorrent, and to what extent. Already there is an ever growing list of bad ISPs available at the Azureus wiki, but the data from the plugin will make their case even stronger.

When the first ISPs started to throttle BitTorrent traffic, Azureus was one of the first BitTorrent clients to introduce a countermeasure, namely, protocol header encryption. However, this was only the beginning of an ongoing cat and mouse game between ISPs and BitTorrent client developers.

Unfortunately, BitTorrent encryption doesn’t work against the more aggressive, and ever evolving throttling applications. Even though there is a Comcast proof BitTorrent encryption in the making, it is always easier to use political means to stop ISPs from messing with our traffic in the first place. The plugin is listed at Azureus’ Sourceforge page if you want to help out.

For the paranoid BitTorrent users among us, Monahan guarantees that the data will be sent anonymously. “Be assured that sharing this data with us does not involve disclosure of any of your personally identifiable information. We will aggregate the data and may talk about it or disclose it publicly, but no data about any specific user will be disclosed as part of this effort.”

How to speed up transfers is a common question from many BitTorrent users looking to squeeze the last drop of performance from their torrent client. Here at TorrentFreak we like to give people as many tips as possible, such as those in some of our previous posts on how to Optimize Your BitTorrent Download Speed and Calculate Your Optimal BitTorrent Settings.

Developers at Northwestern University are also working to improve transfer speeds and have developed an Azureus plugin which claims to do just that – but how? From the site:

“The main goal of this plugin is simple — to improve download speeds for your BitTorrent client. For most P2P applications, the decision regarding which peer to download from is generally arbitrary. When most peers offer good download performance, the random solution works well. However, if most peers are in a different part of the world from you, your downloads can really suffer.

The Ono plugin avoids this by proactively finding peers that are close to you (in a networking sense). These peers generally offer better response time, which can lead to significantly improved performance. We identify those peers that are near you by reusing network measurements from content distribution networks (CDNs), i.e. without performing extensive path measurement or probing.”

According to the project, although the Azureus client is already involved in ‘network positioning’ for increasing transfer speeds, it fails to perform due to inaccurate network co-ordinates. They claim that only 10% of the co-ordinates are acceptable, while 60% had up to 100% errors.

As is the case with Azureus, Ono requires Java to run and can be downloaded here. Anyone wishing to read more about the project should visit their homepage.

Although low latency is preferable in any networking environment, it’s up for debate if in the real world, this in itself leads to faster transfers.

‘Ono’ is a Hawaiian word meaning ‘good to eat’ so we would be very interested to hear if TorrentFreak users find this plugin as tasty as the developers claim, so feel free to add your experiences to the comment section.

Slyck posted an article in which they publish statistical data they received from an anonymous source. According to these statistics uTorrent is more than twice as fast as Azureus, something that I find hard to believe.

Here’s what Slyck’s source reports:

Azureus Mac
Max Rate Seen: 297 KB/s
Average Rate: 235 KB/s
Consumed RAM: 155 MB
Average CPU: 20%

µTorrent Mac
Max Rate Seen: 840KB/s
Average Rate: 698 KB/s
Consumed RAM: 14 MB
Average CPU: 6%

Slyck received these stats from an anonymous source. Probably someone working at BitTorrent Inc because these stats are a little subjective to say the least. It is hard to get differences like this without cheating the protocol, something that Gilles BianRosa, CEO of Azureus, agrees with:

“We are not aware of any such stats, and clearly would doubt their validity. BitTorrent is a standard, and clients have, by design, limited ways to optimize transfer speeds. We have implemented features to optimize “around” the protocol, such as PeerExchange, but getting such wide variations without “bastardizing” the protocol beyond recognition (and making it not compliant/compatible in the process) make these numbers look VERY suspicious, if not ridiculous.”

I’ve been in the position to test an Alpha version of the Mac version of BitTorrent and I also tested Azureus’ Mac version and I came up with figures that clearly favor uTorrent, but not as dramatically as the statistics provided by BitTorrent Inc the anonymous source.

I decided to run my own comparison test using the exact same setup for both clients. The results are based on downloading 3 .torrent files that differed in swarm size and file size. Here’s what I found :

Azureus Mac
Max Rate Seen: 1.42 MB/s
Average Rate: 769 KB/s
Consumed RAM: 130 MB
Average CPU: 18%

µTorrent Mac
Max Rate Seen: 1.28 MB/s
Average Rate: 788 KB/s
Consumed RAM: 16 MB
Average CPU: 7%

The results are quite clear. It is hard to conclude that downloads will go faster with Azureus or uTorrent. Perhaps a difference can be found in a scientific and controlled setting, but no significant difference is observed in a real-life setting. One thing is clear though, the huge difference in download speed reported by Slyck’s anonymous source doesn’t make sense.

What we can see from both comparisons is that uTorrent for Mac, just like its Windows counterpart, uses less CPU and RAM. This is definitely a reason for me, and probably a lot of other BitTorrent users with me, to try uTorrent as soon as it’s released.

Let’s start off with some screenshots.

The Installation Disk Image

Main Window with Downloads

Click to enlarge.

Speed
The main reason I like uTorrent so much is because downloads are considerably faster in it than in any other BitTorrent client. This held true when I compared uTorrent Mac to Transmission and Xtorrent. The downloads speeds in both couldn’t match uTorrent’s. Azureus was the only one that came close, just as I had expected.

Application Launch Time
uTorrent Mac, just like its Windows counterpart, is super-light. It launches immediately (not even 1 bounce in the Dock!). This is clearly one piece of well-coded software. Probably part of the reason why BitTorrent Inc decided to buy it.

Interface
uTorrent Mac has a simple, yet appealing interface that is easy to use and navigate. It’s not as stylish as Xtorrent’s, but then again, no one can create interfaces like David Watanabe.

Search
Though it may seem that uTorrent has some sort of built-in search functionality, currently only offered by BitRocket and Xtorrent on the Mac, it does not. Typing something such as “HDTV” into the search box and hitting return will merely open a BitTorrent.com search page in your default browser.

Conclusion
It’s too early to draw conclusions but it’s a great first impression, especially for a pre-release version.

It’s worth mentioning that some Mac users such as myself like uTorrent so much, we even prefer running it under emulation than using one of the available Mac BitTorrent clients. uTorrent is not only the most popular Windows BitTorrent client according to a poll we conducted last year, but also the winner of our BitTorrent clients comparison.

Many of you are probably dying to download uTorrent Mac. Hang in there, it’s coming real soon.
