steely74 Posted January 28, 2013 Report Share Posted January 28, 2013 edit: pretty sure this is solved. I saw this post It's known issue, try to set net.low_cpu = true in Advanced section of uTorrent's preferences.it's seems to have done the trick. I still see some small spikes up to 10% but nowhere near what i was.I posted yesterday with the issue happening in 2.2.1. I was told there is no support. so I did a clean install of the latest build from the site.I am now running 3.2.3 build on windows home server 2011 (custom built sempron 2.8ghz with 4gigs ram). The other day (using 2.2.1) I noticed very high cpu usage from utorrent. like 70-80%. it is only happening when downloading not uploading.I did a full install, not upgrade to 3.2.3 so no settings were transferred to the new version. same exact issue! I was getting upwards of 70% cpu usage from utorrent!I again followed the steps in the best practice tips A. For fixing CPU-load/memory-issues/Disk-verhead/stability:[1] In pref.->advanced->Disk Cache Make sure : 1a. ->Disable Windows caching of disk writes/reads - are both checked 1b. ->reduce memory usage when the cache is not needed - is unchecked[2] Make sure pref.->advanced->gui.transparent_graph_legend is false[3] Reduce disk overhead by also enabling pref.->general->pre-allocate All Filesit helped but I'm still getting between 10-50% cpu usage on downloads.I have no AV running. I ran malwarebytes and it found nothing. I was using the built in windows defender. Since upgrading to 3.2.3 I have disabled it. I have tried with and without peerguriadian running & with and without dumeter running. same results either way.the homeserver acts as my media box so I can't afford for so much cpu usage nor is it normal!ports are forwarded properly. I have 30/5 internet service so speed isn't an issue. utorrent is just sucking up tons of my cpu during download!! Link to comment Share on other sites More sharing options...
