Hi Paul,
We are pleased to notice huge throughput increases in the qperf/iperf
tests, together with noticeable reduce of power consumption!

This one was identified by your testing efforts, so thank you for giving
me the hints needed to make this change! Looks like some negatives to
go with the positives, though eyeballing it looks mostly positive.
Just out of curiosity, what hardware configuration is this running on?
I am guessing a largish number of CPUs.
Thanx, Paul
