Thanks Eric. I tried to visualize your results - attached.
There are 2-3 odd numbers (labelled with *) but other
than that results are as expected...

I did run some experiments with some udp sink server
and i saw the IPIs amortized; unfortunately sky2 h/ware 
proved to be bottleneck (at > 750Kpps incoming, it started 
dropping and wasnt recording the drops, so i had to slow things down). I
need to digest my results a little more - but it seems i was getting
better throughput results with RPS (i.e it was able to sink
more packets)..

cheers,
jamal
