kraijeck Posted August 14, 2006 Report Share Posted August 14, 2006 This problem is continue from http://forum.utorrent.com/viewtopic.php?id=10791the conclusion isDownloading or seeding BIG torrent (in my case is 157GB) cause somtimes 100% CPU (maybe when choke,snubb,request etc). Selective download about 5GB.if you stop that torrent, problem gone.if you start that torrent again, problem comeback.my computer spec.AthlonXP1700+Mainbord Asus A7V8X-X with sound/LAN512 DDR RamWinXP SP2Clean system novirus/spywareI'm not sure this bug. Because normally torrent would be response to peers request. If that torrent has >40,000 (4MB) pieces, and suddenly over 100 requests from 100 peers come to you for 100 different pieces = 100% CPU?don't worry about this bug because µTorrent din't crash, BSOD, or make error anything (just 100% CPU 1-2 sec). But may cause framerate drop in games/movie.PS. If you have same problem, Please show the biggest size of you active torrent. (8GB should be fine) Link to comment Share on other sites More sharing options...
Ultima Posted August 14, 2006 Report Share Posted August 14, 2006 What are the Disk Cache settings like for you? Link to comment Share on other sites More sharing options...
kraijeck Posted August 14, 2006 Author Report Share Posted August 14, 2006 hmm... let's see, override cache to 20mb (my connection is 512/256; 32mb is too much)reduce memory usage when the cache is not neededenable caching of disk write-write untouch block every 2 minutes-write finish pieces immedieatlyenable disk caching for disk read-remove old block from cachethe other is not selectin advance setting, I chang only halfopen = 36,peer disconnect interval = 450 Link to comment Share on other sites More sharing options...
Firon Posted August 15, 2006 Report Share Posted August 15, 2006 You know, it may say it's a 32MB cache but it doesn't actually allocate that much unless it needs it.Got an anti-virus or fw? Link to comment Share on other sites More sharing options...
kraijeck Posted August 15, 2006 Author Report Share Posted August 15, 2006 OK I got it (even now utorrent use 10~18 MB RAM) KAV6 + Jetico FirewallIf you look at http://forum.utorrent.com/viewtopic.php?id=10791 problem will go even uninstall both KAV and JeticoAt that time I don't know what cause problem. But now I think BIG torrent is suspected (after stop them problem gone). Link to comment Share on other sites More sharing options...
Ultima Posted August 15, 2006 Report Share Posted August 15, 2006 http://forum.utorrent.com/viewtopic.php?id=7385Hm, other people have download large files without complaining. I realize it's only a chat thread with a simple question only, but I think someone would've made a note about it being somewhat of a problem with µTorrent. The only report I see close to yours might've been Enzeru's post, but he was unclear in his post, so I can't tell if it's really similar. Meh, I don't know what else to say.

Switeck Posted August 17, 2006 Report Share Posted August 17, 2006 CPU 100% sounds like maleware co-opting the networking connection and traffic.Even poorly written legit internet-related software might be at fault, such as many software firewalls.

Firon Posted August 23, 2006 Report Share Posted August 23, 2006 It's either malware, a lousy anti-virus, or a lousy firewall. Link to comment Share on other sites More sharing options...
GileraGFR Posted August 29, 2006 Report Share Posted August 29, 2006 I think i have the same problem, not with one big torrent but with about 10-15 smaller (still quite large/equate to the same size as yours) torrents.I also use the Jetico firewall so maybe its that causing the problems, It takes about 15-20 hours for it to go near 100% usage though.I think its time to change firewalls :/EDIT: I can confirm its definatly Jetico Personal Firewall causing my problem, i changed it to allow everything and immediatly CPU usge went down. Anyone recommend a half decent firewall?Thanks to the poster for posting this, it was just what i was looking for Link to comment Share on other sites More sharing options...
kraijeck Posted September 3, 2006 Author Report Share Posted September 3, 2006 to GileraGFR:May be your Jetico rule set for uTorrent is wrong. Or may be some accept/reject in system application cause this problem.If "allow all" can fix problem = some rule set are wrong.If "allow all" can't fix problem = Jetico falut.
