Why is NFS in 2.0.3? slow

It should be reasonably fast.
I have a pair of K6-200's with 96&128M of ram, on an essentially idle
100MB/sec lan, using 3com 3c905 Boomerang cards.

The disk in question is on an (older) AHA2940, which can do sustained
IO throught the linux FS at 6meg/sec.

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.

TCP between the machines runs at 8-9Meg/second.
