Network stack performance

The Iperf tool [1] can be used to evaluate RTEMS networking stack
performance. Iperf works by instantiating an Iperf server on machine 1
and connecting from an Iperf client on machine 2, which will send data
as fast as possible to the server. By first measuring the receive
bandwidth of machine 1 (server) when machine 1 and machine 2 run
Linux, the receive bandwidth of machine 1 when machine 1 runs Linux
and machine 2 runs RTEMS can be used to evaluate the performance of
the RTEMS networking stack.

This might be an interesting project to try to get working (with a lab
setup). Minix/NewtOS used it to evaluate the performance of their
networking stack as described in
