Earlier on this list there was a thread that the CPU usage of iperf was too high (75%..95%). Now, Ingo Molnar has found the problem:

I have tested this and the CPU usage dropped below 10%!

Will go and add this patch before the other iperf patches and upload it to

Yup, Stephen Hemminger also mentioned that a similar patch was already being merged by the iperf guys, IIRC.
