Torrent Transfer Balancing

For some reason, my torrent client (KTorrent) has crappy download speeds but very high upload speeds. I have set a share ratio limit and an upload speed limit, both of which don't appear to be working. Is there some way I can configure the client to be more fair or something at the network level I can do?

Don't bother with comments like "Use a different client" because they'll be ignored.

Time to start listening to posts about using a different client app then isn't it, faggot.
