bottleneck Posted September 27, 2007 Report Posted September 27, 2007 Over the last few days i've noticed that while playing a game I get a lot of lag so I went to check task manager to see what was causing it and found uTorrent to be the culprit.I don't have any anti-virus or anti-spyware software which could be causing a problem, i've tried numerous different settings in uTorrent to try to reduce the CPU Usage and it doesn't seem to fix it.It can't be anything to do with the cache reading (I presume) because it happens while seeding and downloading and I have it set to default cache sizes.The only thing that could be causing a problem is the 400+ torrents I have imported into uTorrent, 60% of these actively seeding but only about 5 actively uploading to peers. :/EDIT: I also noticed people have been having problems with programs hooking itself to uTorrent so here's a screenshot from Process Explorer.
DreadWingKnight Posted September 27, 2007 Report Posted September 27, 2007 What is your hard drive's current transfer mode?
bottleneck Posted September 27, 2007 Author Report Posted September 27, 2007 They're all set to either Ultra DMA 5 or Ultra DMA 6.EDIT:After reading through the F&Q i've realised it was because of this.If you don't have this firewall and still get high CPU use (either utorrent.exe, or an unseen process), run Sysinternals Process Explorer and see if the DPCs are using significant amounts of CPU. If this is the case, it may be buggy software (most likely not µTorrent), buggy drivers, or faulty hardware. You can run Microsoft's RATTV3 to find out the cause of the DPC. The log files from it are stored in C:\WINDOWS\system32\LogFiles\RATTV3
daedalus007 Posted October 13, 2007 Report Posted October 13, 2007 I think I might be having the same problem, but I'm not sure how to fix it. My cpu spikes every 15 minutes (almost exactly).I've downloaded RATTV3, but I'm not sure how to interpret the output.

It's a real pain trying to watch a HD movie if it stutters every 15 minutes. Thanks.
Firon Posted October 13, 2007 Report Posted October 13, 2007 That doesn't seem right. RATT should provide much more info, including ISR/DPC counts for each driver.
daedalus007 Posted October 13, 2007 Report Posted October 13, 2007 Yea, that's what I thought from reading the RATTV3 manual. I forgot to mention that I'm using Vista. Maybe RATTV3 doesn't work properly with it.I'm not sure if this is related but whenever zonealarm is running, vsmon.exe (the firewall) cpu usage is always at 100%. Recently I haven't been using it, because of that reason. I'm going to try uninstalling it altogether to see if it helps.
Firon Posted October 13, 2007 Report Posted October 13, 2007 Ew. Zone Alarm is known to be quite problematic with P2P in general. Uninstall it ASAP. Outpost, Sygate and Comodo are decent firewalls.
daedalus007 Posted October 13, 2007 Report Posted October 13, 2007 Well, Zonealarm is now gone and uTorrent's been running for more than 15 minutes w/o anymore cpu spikes. Hopefully, it'll stay this way. Thank for all the help Firon.
Ultima Posted October 14, 2007 Report Posted October 14, 2007 Yuck, ZA's gotten a lot worse than I imagined... :| Lucky I ditched it when I did O.o
