nfsd 4, why, and how to tune...

[Eric Wedaa]

Does anyone have any ideas on how to tune the nfs daemon "nfsd".  I'm calling
it with the recommended call (nfsd 4) but my server stil gets a bit slow
when folks start doing makes across the net.  Any recommendations on how
to come up with some standard performance figures so that I have some 
way to reliably measure my changes?  Or am I just being overly sensitive to
the users and their comments on performance?

The following was made this morning when the local system was relatively
calm, and a series (6) of 'find / -name core -print' was being run on one of 
the clients.
