i suspect that it might be that some isp's cap the speed on p2p apps.

I have no problem with Bittorent,

But I don't have use it since two weeks now ;)

I agree with you however how could they be able to distinguish which are p2p progs or normal transfer aside from the ports since there are so many varying ports for each?

Had no idea what BitTorrent was - thanks for the post. For anyone else who wants to learn more (there must be one or two of you) , this seemed to be a half decent tutorial:
