Where I live in the US we have ADSL and to make peer-to-peer viable at all I have to put an upload cap on, otherwise the uplink gets saturated and downloads start having problems because the ACK packets get delayed or lost.

It drives me absolutely up the wall that some torrent networks insist that you have a 1-1 ratio because it is close to impossible for me and there is no point because often the network has so many seeds…. The fact that I can complete a transfer uploading just 5% of what I download proves my upload isn’t needed.
