NFS faq

NFS faq

[J. Bruce Fields]

Do you still maintain the FAQ at nfs.sourceforge.net?

In A7:

	"There are some minor interoperability issues when applications
	running on clients make use of some of the new features of NFS
	Version 4 such as mandatory locking, share reservations, and
	delegations."

I'd remove "delegations"--they change the performance (most dramatically
if the server has to wait for a lease to time out to allow an open), but
should otherwise be transparent to applications.

The

	NFS-related kernel patches supported by Trond Myklebust
	NFS-related kernel patches supported by Neil Brown 

links should probably just be removed and replaced by a "linux
development" link to linux-nfs.org.

There was a discussion I initiated some months ago regarding setting the
queue sizes that contained some good information on the subject for
performance; The original script referenced a /etc/sysconfig/nfs file that
RH 8 began referencing, but included a good conversation on what the queue
sizes should be set to, and how kernel 2.4.20 was now setting those sizes
automatically. I saw a 15% performance boost in a single large file copy,
and also a significant but not quantified boost in a more dispersed NFS
system.
