Roland,
I have applied this patch and updated patch 2/2. You will send out an updated patch 2/2, I think.
I did some extra modification in ipoib code, (which has more extra repolls). I do see around 10% or more performance improvement now with this change on both scaling and none scaling code. I will run oprofile tomorrow to see the difference. I think with these extra repolls, the cpu utilization would be much higher.
Thanks
