Processor overload with Iperf

[Santosh D. <drs...@gm...>]

Hello,

I am intending to use Iperf for testing my QoS rules and policies on a
network switch.
However, I observe that when I run Iperf on the switch (with *Linux 2.6.10*),
the CPU load shoots upto 100%.
I have been looking for Iperf patches that result in improved CPU load, but
haven't found any yet.
I am using iperf version : *iperf version 2.0.2 (03 May 2005) pthreads*

I'll be greatful if somebody can lead me to suitable patch/solution that
helps in having Iperf consume lesser processor bandwidth.

Thanks in advance.
