Hey, I'm running this version on my new server. There's not a lot of software running in the background (just WD button manager for my external disks and RealVNC), I didn't even install any anti-virus software yet. It contains a Phenom 2,2 GHz quad core (x9500), 4x 1GB RAM, 3Gbit/s SATA, the torrent folders are on an internal hard drive. My torrent list got 2 running downloads, one stopped downloaded, 2 running uploads and 4 completed downloads waiting for an upload slot. Not a big list. However, sometimes uTorrent can get slow like molasses. Considering I have this pretty powerful machine mainly for uTorrent and file sharing for my LAN (not very intensively at the moment), I can't come up with any reason why something would be limiting the application. I checked: I got the latest stable release (it can't find any updates when checking). I'm running Windows 7 Pro x64. Any ideas what could be the issue? On my laptop (Phenom II mobile, Windows 7 Pro x64, 4GB RAM), the same version of uTorrent (3.0 build 25806) doesn't have any issues at all. I saw some people reporting issues with disk reading/writing going bogus. So far I don't see that occurring in my system (but right now it's not showing the slow response issues). Thanks in advance!
