Exactly 320 kb/s for me too:)
This is 10 times as fast as Bittorrent. It may be a good idea if you do have bittorrent, to seed the file even if you did not get it using bittorrent. To do so (at least in azureus), just copy the complete file over the file being downloaded in bittorent. In Azureus, do force recheck, and it will see that you have the complete file and start seeding.
