Go get the latest release of the bit torrent engine. There are quite a few improvements, especially on the bandwidth use of the tracker. Note that you might have to re-associate bit torrent with your preferred client after installing this, it will probably change your .torrent associations back to the default client. My client of choice is Azureus, which is java-based and thus runs on any OS. And as a bonus, they happen to have a new version out this week as well. Get downloading!
