That looks right. 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,
