And some hints about good speeds:

Swarms with a bad Seeds:Peers ratio - especially small ones - usually have bad download rate, thus try to run them in parallel to other torrents
A forwarded and unfirewalled port is important, use the the NAT-Check to verify if your port is reachable, just look if your torrents have green smilies ()
or simply put in your port here and press enter. If it doesn't report that your Port is "Open" either the forwarding or the firewall settings are incorrect.
Use a random port between 50000 and 60000 for incoming connections
