I am running uTorrent 1.6.1 and I noticed that my torrents up and down speeds went into a crawl when ever I was downloading and/or seeding more than a few torrents. The box used for teoorent is fast enough and has 4GB of RAM, and I got a 10Mbit/10Mbit connection so what could the problem be?

I got the idea that it might be something to do with the disk, so I did the following I went into Options->Preferences->Advanced->Disk Cache and unticked the box that said “Reduce memory usage when cache is not needed”, I ticked the box that said “Override the automatic cache size and specify the size automatically” and I entered the value 128MB. There you go, the speed appears to have incread about ten times. I will leave it to someone else to explain why.
