1) How to correctly tune nfsds.

	Hal Stern's book "Managing NFS and NIS" is absolutely correct in
	his suggestion that you monitor socket buffer overflows on the
	server.  This is the best way to determine when to increase the
	nfsds.

2) Does increasing number of nfsds hurt on an SS1+ because there are only
   8 hardware contexts?

	No, each nfsd runs in the kernel's hardware context, context 0.
	Context switching between nfsds doesn't result in any hardware
	context flushing activity as hardware context 0 is reserved solely
	for the kernel's use.

I apoligize for any mix ups.
