Not sure if this has already been reported but my download speed with a few active torrents bounces between 200kb/s and 1600kb/s if the program is running at the background but when brought to foreground, download speed is steady 1600kb/s. I also get the Disk overloaded xx% in the bottom bar. I have not limited my download speed. Edit: never mind about the first part. DL speed seems to drop when Disk overloaded message appears. Edit2: uTorrent reported a couple of hangs.
