I currently get 28 mbps download and around 8mbps upload (I'm supposed to get 35 Mb D/L 15 Mb up). I have fibre optic (BT Infinty), it's pretty good. In practice it means I can download 3Gb in about 15 mins via PSN. A good torrent to my PC flys down.. 200mb file in about 10 seconds
I'll definitley be hosting some Birds of steel games, not really hosted many BoP games, I let the regulars do it. Maybe next time there's a few on I'll try hosting and see if it makes a difference.
