The windows of time which the 850 MB/s performance, are kind of hard to 
track so I can't give a confident answer, from some looking it seems 
that yes, the CPU utilization gets higher when the bandwidth is high. 
Also when running two netperf sessions and irq daemon off, I tend to get 
constant 700 MB/s which is better then the constant 620 MB/s I see with 
one session.

Very much appreciated.
