Vuze vs uTorrent

Vuze and uTorrent Comparison

There are two freeware BitTorrent clients that really stand out from the crowd: uTorrent and Azureus (now known as Vuze). Since these are the most popular ones, it's only natural that a lot of people argue about which one is a better torrent downloader: Azureus or uTorrent? Both of them have their pros and cons, some of which are listed below.

Both clients, however, are fully capable of creating, downloading and seeding .torrent files, as well as doing a lot of smart and advanced things like automatically downloading from RSS feeds, using multiple trackers, banning specific IP addresses, or setting download priorities for each file inside the torrent separately. You probably can't go wrong whichever one you choose for your torrenting.

Vuze (Azureus) Overview

Vuze compared to uTorrent

Azureus is a powerful open source BitTorrent client with a huge amount of features and support for 3rd party plugins. For several years now it has been known as Vuze instead - a P2P (peer-to-peer) network of high quality video content - but you are still able to use the classic Azureus interface if you want to.

Vuze requires Java Runtime Environment (JRE). This is good because it can run on any operating system that supports JRE, and it is bad because Java-based Azureus client uses quite a lot of system resources. Many people say that Vuze downloads faster than uTorrent, but tests have been conflicting so far and there's no definite conclusion.

Vuze recently released a new torrent client called Vuze Leap. Compared to their original app, it uses a lot less resources and features an extremely simple GUI. It might appeal to people who found the original Vuze too bloated and slow.

uTorrent overview

uTorrent compared to Azureus

uTorrent is a lightweight and efficient torrent downloader. It is closed source, which Azureus fans are quick to point out as a big flaw (it is theoretically possible for the uTorrent developers to add anything they want to the program, such as DRM protection, or copyright breach reporting, without the users' knowledge). There's also no plugin support, and it has less features than Vuze (but still more than you will probably ever need). The latest version has some ads running, which fortunately can be disabled through options.

Unlike Vuze client, uTorrent is not Java-based. This is good because uTorrent is really small, fast, and uses very little CPU and RAM. However, it also means that a separate version has to be developed for every platform. uTorrent now has Mac support, and an early Linux version is in development. There is no doubt that uTorrent is faster than Azureus when it comes to the program itself; on the other hand, various Azureus and uTorrent speed comparison tests have shown different results, so it's not clear which torrent client can produce higher download speeds.

Best BitTorrent Program Poll

I've always used utorrent and mostly reach max speed for either upload as download, according to the max speed my ISP has to provide me (and it usually does so according to some independed speedtests). If I don't reach max speed it's b/c there aint enough seeders or leechers, or they don't have high upload speed. Utorrent is effective for me (for downloading torrents and upload them for 150%) and when utorrent is minimized in the system tray I hardly notice it. Otherwise I'll lower bandwith allocation.

think4urself on June 01, 2014:

utorrent is terrible! It took me over an hour to download 50% of a 400 mb file. Got so frustrated in reinstalled vuze and had the same file downloaded in 15min!

Amine from Doha, Qatar on February 11, 2014:

I use utorrent, torrents world is the amazing thing in download so far

@anonymous: true :)

Having said all, I really gotta appreciate this comment somebody put here: "if it wasn't for the icon in the system tray, I wouldn't even notice if UT is running."

Hell yeah! Even when downloading about 5 torrents, ~5GB each!

Wanted to suggest you to try to embed this social debate -

It's pretty cool!

've used been using torrents for ~decade and have always used a version of utorrent. Recently vuze has been recommended so I've decided to try it. Migrating ~100 torrents was a total pita (by the way for some reason Vuze flagged some files as failing hash even thought the checked out in utorrent and I've tested files myself as good) but I've finally manged to do it as well as tweak its 9999999 options and turn off all the stuff that imo should not be in a torrent client players/dvd burners/media server/etc. Anyway after running it for 2 days here are the issues I've encountered so far

1. Vuze does not want to quit out after running for a few hours and I have to terminate azerus.exe through task manager which in turn causes it to recheck the unfinished torrents on next start - total pita

2. Vuze does not download some torrents (that download fine in utorrent I've checked) giving Error: NullPointerException.

3. Large single torrents with file sizes over 30 gigs seem to be very glitchy aka crushing the client while loading

4. All in all it seems to glitch/crash a hell of a lot for a torrent client also use immensely more RAM which I don't really care about but still.

back to the utorrent for me. I much rather use a program that does not include random glitches.

anonymous on May 05, 2012:

uTorrent>Vuze. my friend has vuze and he has problems on and off. utorrent is so much stable, and quicker to open and run. speed of download depends on the peers and seeders, not the client. your internet also limits it.

anonymous on May 01, 2012:

Just tried to download same torrent with vuze and utorrent. Utorrent was about 10 times faster. Plus I have noticed when I use Vuze the entire broadband connection slows down dramatically, including on other computers from same network.

anonymous on April 29, 2012:

@anonymous: Still i really want you to show me 400+ ACTIVE torrents in Vuze :)

And for Vuze to not destroy your harddrive you need memory buffer + java's memory buffer for vuze's memory buffer = a lot of memory to run a network client ?

P.S. Under active i don't mean torrents with status "seeding" but torrents with actual transfer.

anonymous on March 12, 2012:

uTorrent is like stale crackers in an old chili. you wouldn't want to dump a bunch of that STUFF down your drain!

anonymous on March 11, 2012:

Of course uTorrent is better. Firstly it takes seconds to start up, Vuze takes the best part of 30 seconds. Secondly, without trillions of useless config options, such as what colour you want the download bars, uTorrent has a small footprint and thus runs faster. Thirdly (not lastly either), uTorrent actually downloads magnet links, unlike Vuze which has refused to work properly since it became Vuze instead of Azereus.

anonymous on February 27, 2012:

can utorrent stream to any device? didn't think so

anonymous on November 28, 2011:

i have been using both clients for some time and i want to share my experiences.


- very lightweight "using very little system resource"

- average 10k - 50k memory used even downloading multiple torrents


- can slow system down because its java based and can crash java sometimes

- use more system resource when downloading multiple torrents/files

- 50k - 150k based on usage

to those who "got a virus", "system crashed" , "computer hang" etc etc....only vuze can slow,crash or hang a computer since its java based. you can only get virus when downloading bad files. its not the softwares fault, its the users fault for downloading a virus, so don't be a fool


- software is not to blame. blame your connection for being slow and undependable. and a download speed is as fast as the seeders and how many are seeding the files.

anonymous on October 12, 2011:

Vuze is ok as long as you are not using your pc while your downloading as it uses up a lot of resources, utorrent on the other hand is lightweight, a little slower downlloading but not by any signifant amount uses much less resources but not as customisable for me I prefer utorrent as I don't use any of the plugins that vuze has but still a good program

anonymous on August 27, 2011:

Vuze is always better than utorrent in terms of speed..

anonymous on May 09, 2011:

Most people look for speed, simplicity and light-weight download. uTorrents offers that and I guess most people are satisfied with it.

Vuze is open source and has a few more features than uTorrents (I heard). It is attractive, since a person like me would have an opportunity to dig into its code :)

So I compare them from different level. As a normal user, I prefer uTorrent. As a developer or as person seeking extra options, Vuze would give me that.

anonymous on May 05, 2011:

utorrent is my choice. maybe vuze has built with advanced for searching torrents, downloading, receiving updates etc. but u torrent is one user friendly. thanks for this comparison.

i invite you to visit out site for mac data recovery software for recovering your lost data.

pointer lm on May 04, 2011:

Wow! You have provided excellint information about torrent agents. presonally I like Veze it is the most powerful torrent software and very easy to work with. Youâve put lots of useful information inside, thank you. Please visit my lens titled Download HD Movies and tell me what you think about it.

Regards to all and God bless

thanks for the info, new into the debate, you provide a great starting place for newbies such as myself

anonymous on January 02, 2011:

@anonymous: It depends a bit since every program has different algorithms on which peers / seeds to connect to, etc (I think?). For example uTorrent has this new thing called "µTP protocol" which is supposed to automatically slow down the downloads when your network is busy to reduce latency, and get through firewalls easier. Check this out:

anonymous on November 07, 2010:

Are you actually saying that speed depends on program itself ? it will depend if the program is written in the worst possible way ... everything other is about network configuration ... and i used vuze ... if you want to just download and not be able to do anything else (simple math java resources + memory buffs for cache = no resources left (speaking 10MiB/s+ speeds)) use vuze ... if you actually want to add and forget about torrent (ratio based trackers) well you have no other choose than utorrent :)

anonymous on November 01, 2010:

love the debate :)

@lilmuchang1: uTorrent runs on Mac. I have it. It's called uTorrent Mac.

anonymous on July 07, 2010:

It's funny how so many people have to trash the program they don't use. It makes they're position invalid because they're too emotionally involved, instead of being logical.

I think both are good clients, but I use utorrent for a few of reasons: (1) utorrent was the first one I tried and I'm more comfortable with it; (2) I don't use most of utorrent's features, so I don't need even more; and (3) I can be downloading a torrent with utorrent in the background, and still scan documents, write DVD's or whatever. It doesn't slow down my machine and if it wasn't for the icon in the system tray, I wouldn't even know it was running.

lilmuchang1 on May 31, 2010:

I'm using Azureus cos I'm using macbook! Great lens you have there. Visit me at

anonymous on April 06, 2010:

@anonymous: I've always used Azureus: free, highly customizable with a ton of plugins available, downloads fast, etc. But I agree that this Vuze thing is crap. All I want is a torrent client not some stupid "content network".

Luckily you can use the "old" interface with a simple click. However all that bloated stuff is still sitting there and eating your resources.

anonymous on February 26, 2010:

uTorrent is good enough for me. Vuze is full of shit that I don't need, like the "HD Network" stuff. It also doesn't seem any faster than uTorrent. So, if you're looking for a basic BT client, use uTorrent. If you want the Vuze shit, use it. Plus, uTorrent has customizable icons, so there's no war between looks.

Thanks for the info's guys...

Nice review about torrent cilents

Adrienne Jenkins on July 03, 2009:

Chadrew...appreciate your disclaimer about the no-nos of sharing copyrighted material.

anonymous on June 08, 2009:

I downloaded and installed Utorrent, and being a longtime Vuze user, I could use some help understanding how utorrent compares or even works:

In Vuze, I search a keyword of what I'm looking for, and then I sift thru all the choices, choose, and then download.

But it seems like Utorrent searches for torrents but doesn't actually provide the download? I don't really get it.

Andrew Po (author) on May 24, 2009:

[in reply to CURIOUS]

Only some anonymous usage statistics, and only if you've checked the checkmark in your Preferences (otherwise it won't send anything). Now, since it's not open source, no one except the developers know *for sure* what uTorrent is reporting... But I think there's no reason to worry.

anonymous on May 23, 2009:

Whats exactly can be passes around with out our knowledge if one prefers to use utorrent .. any knowledgeable input would be appreciated

Treasures By Brenda from Canada on April 07, 2009:

I'm afraid I do not have enough knowledge to comment on Azureus or uTorrent. Nicely done lens though!


anonymous on March 19, 2009:

DEFINATELY uTorrent!! VUZE is good if you're not using windows because it's the fastest for non-windows machines, but if you have windows (as most people do) then uTorrent kicks VUZ's ass! either way, don't take my word for it, download them boath, and test them both on the same torrent, then you'll get an idea! they're both free and easy, so why not!??

anonymous on January 01, 2009:

Funny how things turn out, I remember BitTorrent being the biggest and most popular client out there. Now they kill it and start using uTorrent as the base for the official BitTorrent client. Basically all they do is re-brand it and rename it to 'BitTorrent'. So yeah, uTorrent is most popular for sure with Azureus aka Vuze possibly taking the 2nd place.
