I get 500k/sec for NFS traffic. This really sucks.
Doesn't seem to matter Read or Write.
I don't do TCP/IP. I don't set any block sizes, just use defaults on
the mounts.

That is pretty horrific, I do agree. I remember that when Olaf first
coded up the new NFS code he was able to get ~4MB/s NFS in the lab of
Linux boxes last year at Linux Expo. Whether he tuned parameters
etc. to get that, I don't know. If he did, we need to investigate our
default parameters a bit to see if we can find more suitable settings.
