I'm having the same problem too on C&W. When I do a speed test from Speakeasy. I keep getting a constant 20,560 kbps which is my full 20 mbps and about the same on the upstream side. But when I am downloading from Revtt, FTN, LL, iLT, SCT, TB, no matter which one of my private trackers I use I don't get anything more than a 4,701 kbps (587.6 Kbps transfer rate) which is roughly 5 mbps. So I was really pondering the thought, that maybe they are indeed capping p2p downloads. Because all other downloads come through at it's rightful speed. My Client is properly configured and there are more than 20 seeders at any given time, my ratios are in excess of 2.5 with VIP status. So I'm not sure what happening.
