Sure, I'll do it as an experiment. Got any suggestions on how to do that? I tried to decrease sk_pacing_shift even further with no effect, I've also tried many more TCP streams with no effect. I don't even care about a single flow that much, honestly. The default test is like 10 or 20 flows anyway. > If only TCP could predict the future ;) :) johannes
