	While NFS activity can certainly bog down due to network loading,
we resolved a lot of sluggishness on our PC's by checking all the cable
connections... it seems that the temporary student who put much of the wiring
in place couldn't solder very well, and also didn't know that there is a
significant difference between RG-58 and RG-59 cable. We replaced the bad
cable, fixed a few connectors, and VOILA!, most of the network delays 
vanished. Now we only see it when one of our diskless machines decides
to compile emacs or something like that... you might try looking at
collision statistics to figure out if it's the cabling or not.
