I changed some of the test params, here: now I am over a gig-e link
and switch instead of 100Mbit.

Performance: 16-18MB/s very steady. Load on server: around 9. I have 8
nfsd configured.

I can live with 17MB/s. I wonder if I had a hub/switch/whatever go bad
and start to flake out when under load. You may safely ignore this
thread.
