There have been a few fixes since, but mostly cosmetic and shouldnt affect the results. Strange - so far your results contradict both mine on pktgen (since you show poor performance sometimes) and what Krishna posted on netperf (since you show improvement). BTW, on pktgen and batching - dont use the clone parameter for anything > 1. I have not tested that code-path at all and it is highly likely buggy. Thanks a lot for taking the time Evgeniy. cheers, jamal
