Seems that when uTP is selected, the UL is maxed to beyond my defined max, and kills my poor 20K UL connection in spite of the uTP theory... Keeping to the defined limits - IS important until this release is stable, otherwise it may become useless for low UL bandwidth connections. Also changing of the advanced setup seems to have no effect on the UL limit control until you restart uTorrent. Not sure if calc_overhead has any effect here... Downgrading to previous release for now...
