FWIW, we (hi, Darrell!) helped discover this about 5 years ago on an F330 that was grown from 2GB drives to a mix of 2GB and 4GB drives. (We beat the snot out of that box; it averaged over 700 NFS ops/sec 24x7 for over two years...)
At the risk of starting a "mine-is-bigger-than-yours" or a "I've-got-it-worse-than-you" [0] war...
That's not beating the snot out of an F330. *This* is (see Apr/May timeframe):
ftp://ftp.mathworks.com/pub/tech-support/incoming/toddc/F330.nfs.snmp-year.gif
MRTG one-year graph, one-day average: MaxNFS Ops 1713.0 ops, AverageNFS Ops 1047.0 ops, CurrentNFS Ops 717.0 ops
Add another ~200-250 ops/s for CIFS traffic, too.
We hope the replacement F840 arrives before this poor F330 bursts into flames. With that kind of traffic, we're gonna have to find more stuff to put on that filer 'cause the F840 is going to be bored out of its mind...
(We stopped the NFS traffic growth by implementing CacheFS mounts on many of our UNIX boxes. <whew!> That bought us quite a bit of time.)

Until next time...
