    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.)
