Hi I aint on sky yet, but use three well known torrent clients, Bitcomet, U Torrent & Azureus..
U Torrent i find gives the best speed... I get the full speed (on my prersent ISP MAAF)just a few tips (if ya aint done it already)
Make sure you set up a port, look at
www.portforwarding.com for help with your router. Also make sure your firewall is not blocking ya connection in anyway..
Also I believe by default Installing SP2 limits your TCP connection attempts to 10 whereas there wasn't any limit in SP1. MS supposedly did this as a security measure. You can increase this using a tool here :
