I've been struggling to download a 71GB torrent since the beginning of February. It's been downloading at between 0.5 - 1 GB every 24 hours on a 4mbps account. So yesterday morning I got a Gold uncapped trial account from OpenWeb and it downloaded at line speed all of last night. Says it all really.
I cancelled my MWEB account this morning, even though it will still run until the end of March, and have signed up with OpenWeb.
I'm very inclined to do the same at this point. The last few weeks have proved rather pathetic, but more so for streaming than torrents (which are dead 80% of the time anyway).
