That's what I should've said if I wanted to be helpful. On Linux I
suggest iperf (multiple threads) or multiple concurrent copies of
netperf. It takes more than one thread to saturate the link. Then after
you made sure that works, then you can go on to seeing how slow NFS
really is.

On NetBSD I'm not sure.
