Well, what does 'vmstat 1' show - how many context switches are there per second on the iperf server? In theory if it's a truly saturated box, there shouldnt be many - just a single iperf task running at 100% CPU utilization or so.
(Also, if there's hrtimer support for that board then perfcounters could be used to profile it.)
