torrent eat 1 cpu core

uninstall/install 3.0 or 3.1 version didn't help

i noticed when there 0 torrents in list, CPU usage is low, then i add 1 torrent file

torrent start checking already downloaded files on my hard drive, during this time CPU usage hold on ~10% (i have 4 core cpu, 25% if full usage of 1 cpu)

after he over checking files there are few seconds when usage go back to 0%

but when torrent file start uploading even with speed 5kb/s , CPU usage rise to 25%

my system win7 64

Same problem.

Windows 7 x64 SP1, 4 Gb RAM, Intel Core 2 Duo 2.27 GHz

uTorrent 3.0 (build 25756) [32-bit]

uTorrent consumes one core completely (so in task manager it shows 50% cpu usage), dl speed is about 10 KB/s. Sometimes (a very rare case!) it works fine after closing uTorrent, killing that process and starting it again. Still, it starts to consume 50% and dl at 10KB/s again after a while.

Changelog:

-- 2011-10-27: Version 3.0.1 beta (build 25854)

-- 2011-10-20: Version 3.0.1 alpha (build 25829)

- Fix: Hang writing partfile for multifile torrent containing a file > 4GB

This was the cause. ... you should all upgrade to 3.01 IF this is your symptom!

Right, I forgot to mention my CPU type: C2D E2180 (~2000Mhz) . "at maximum" ? with 1-2 torrents ? Maybe your connection bandwidth is much higher than my 500K :( you should really look into other apps that might be effecting that - AV/Firewall and such.

btw, I am planning to do more complete comparative tests for performance in a few days...

Yes, it happens with 1-2 torrents. My bandwidth is 6 Mbit. AV/Firewall? I have only nod32.
