rafi, bear with me, I'm still struggling with this. For my percentages, I was talking about the % of my overall UL, whereas you were more properly talking about % overhead relative to DL. That aside, I can only increase UL so far so can only test this so much, but how do you explain my overhead raising commensurately with raising my UL limit? In the above example, I doubled UL to 100, my DL wasn't much affected, yet my overhead doubled as well. If I could raise it to 200, would it double again? If so, this is more than simple ACKs. In v2.00, didn't the "Up Speed" column for each torrent show a real UL value (assuming net.calc_overhead was set appropriately)? Just as v2.01 does? I realize v2.00 didn't have an overall overhead figure.
