Ugh. That makes sense since I was downloading 4 torrents at once. It's gotta be partially torrent related too because I've downloaded many many large files via web browser (FF and Saf) and it never happens when my speed goes high. For example, I've downloaded Ubuntu at my max ISP speed (700kB/s) as a test, and it was fine. Did this numerous times actually. This is really discouraging. I don't think it's limited to Transmission either because I had weird issues with BitRocket and TomatoTorrent in the past. I find it hard to believe that thousands of real mac users and/or the hundreds of Intel hackintosh users out there have problems with torrents like we do. What else could this be???
