There is a lot to be said for the RaspberryPi, but network throughput, and
especially processing power are limited. My tests show that the RaspberryPi
could push only about 46 Mbps of iperf while most PCs configured the same
way get almost to wire speed (100 Mbps or 1Gbps), and processing 30 seconds
of 45 Mbps traffic on the RaspberryPi takes many minutes. But, if you want
to test slower circuits, it can't be beat for cost, size, flexibility.

I am expecting delivery of a Parallella board in October and will be
testing it for iperf capability at GigE speed.
