Maybe its bitcomet? i dont seem to have any problems when i download torrents, i dont use bitcomet either.

A reasonable exaplanation though would prob be the amount of seeds your connecting to (i think its seeds or peers, i always get the two mixed up)

If your connected to a lot, then your splitting the d/l speed across all of them, its probably hogging your speed for other stuff like browsing etc.

But my advice is to try another torrent program first.

Yeah check your uploading speed and maybe be a jerk and set it to 1KB/s max.

strange, id of never thought about that cos mines on unlimited and i never have any problems, oh well!

That's what happened to me.  I was uploading like 100 KB/S and downloading 10 KB/s.  I set my upload max to 1 KB/S and then I was downloading 300 KB/S.  

@bluev8killer: That's because that's how the internet works.  Let's say you have 1 Megabyte download speed.  If you're downloading a 950 Kilobytes per second with a Torrent, the rest of your download connection will slow down because your browser would only be able to download websites at 50 Kilobytes per second.
