Thanks KK.
Folks, we need help. Please run this on different hardware. Evgeniy, i
thought this kind of stuff excites you, no? ;-> (wink, wink).
Only the sender needs the patch but the receiver must be a more powerful
machine (so that it is not the bottleneck).
A very interesting test will be say 10K flows serving different packet
sizes to simulate a busy server.

I realized i cant really run the sort of tests KK is running because i
dont have the second machine. With pktgen i have an easy way out because
i can drop all the packets on the receiver and just count them (whereas
netperf requires end 2 end semantics).

cheers,
jamal
