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.

If you're behind a router or firewall make sure you have your port forwarding set up properly.  The reason why switching clients will normally work is because the default ports used are limited by most ISPs because they are known to be used for downloading.  Try to change the port, then forward it. Chose a port in the 40000+range. If you're behind a router, plug in direct to your modem.
