Yup, that's the problem with P2P and why I'd only use it as a last resort after Newsgroups and Torrents.
With P2P as the name suggest (peer to peer) your download speed is limited by the others upload speed so is never likely to be very fast. With torrents you are taking advantage of the upload speed of several(sometimes hundreds) of other users at the same time. With Newsgroups you are using their dedicated servers which have high upload speeds by default.
