this is me being lazy but i'll ask all the same...

i've just started using azureus and utorrent (they seem to be popular things to talk about at the moment around the blogs) but i'm wondering if it's normal for the cpu activity from these torrent managers to be at 50% all the time - that just seems crazy to me.

i was just trying to get some noam chomsky videos but i'm not going to bother if it means 50% cpu activity constantly as they download.

can someone please confirm if that's normal or is my machine just freaking out.

No, you're not crazy.  I used azureus for a long time, and found that it hogged my cpu.  Actually, that's why I turned to utorrent, but I think that is pretty heavy on my cpu as well.  I like utorrent because it's not java like azureus and clicking around things is faster and it feels more lightweight.  However, azureus is more feature-rich, although I don't think I use any of the fancy features.

But back on topic, I don't know if it's the nature of torrents or what, but these programs do seem to use a lot of cpu.  Maybe there are other alternatives, like ABC, which I used a little bit, but it seemed to download slower than azureus and utorrent.  On the positive side, azureus downloads the fastest of them all I think, with utorrent almost there also.

Maybe because the download speeds are approachin 200-300 kBps is what is making the computer slow.  Does anyone know anything about that?  I've heard that when you download anything at really high speeds, the computer can become significantly slower.  Is that true?

I've only used utorrent a little, but durring that time I didn't notice it using a significant percentage of my CPU. I used to use Azureus, but then I remembered that I hate Java and went to Bitcommet. I don't know how Bitcommet stacks up against the competition in regards to CPU use, but I've accidently left it on a couple times when playing Counter Strike, and not realized it until after I left the game. Of course, the download speeds I was getting were very low, so maybe that is why I didn't notice it using up my processing power.

Hirudin, so you're a fellow java hater also?  I'm not a programmer or anything, but why do java applications suck so much?  I don't know why, but they just do.

Hmm... must be that they're written in Java!!!
My issue is that it trys to be everything to everyone and is so complicated to develop with and distribute, that it ends up being fairly worthless. 

Your mileage may vary. Wink

The problem with java apps is that java doesn't work like C, and you when you don't want something, you don't destroy it, you abbandon it, and then the garbage collector will come and clean it when the memory usage is too much. This one of the main aspects that tend to make java apps resource-hogs.

uTorrent should be pretty light on resource.
In my PC it has about 3MB allocated after hours of running, and CPU time is around <=1%.

Bye!

It's written in c++ and runs very smooth smiley

BitComet is more of a leecher tool, and is widely banned by trackers and other peers for various reasons (Not respecting the private flag, not uploading much data, etc)...

As for Java being crap, well, I quite like it, it's often taken for granted that fact that a program can run on almost any OS with absolutly no re-coding... Sure, it's not as light as C or C++ (Although, those complaining about Azureus using too much memory: http://bluescreenofdeath.co.uk/Temp/Memory.png ) but it serves it purpose...

It's not a bug, it's an undocumented and unexplainable feature.

interesting. no definite answer but at least i'm not the only person experiencing high cpu use. i shall now go away into a dark corner and meditate on whether to use these torrent things - bitcomet is perhaps the path to take.

Speaking of BitTorrent... anyone can recommend a Win32 one that could be run as a service?

If you restrict the number of connections azureus opens it will use less CPU time. There are other ressource-optimizations you can undertake, they are laid out on Azureus website. But it does use some amount of memory...
