NFS packet size

[Herb Barad]

We are having some NFS performance problems.  We now have some machines
located in different buildings with a couple of routers in between them.
There's not much traffic and I know the net is working fine since FTP fly
real fast.  However, we very often get NFS timeouts.  This is especially
true with large files (e.g. executing emacs when the binary sits on the
remote server).

I've tried changing the packet size via the mount entry in the /etc/fstab
file.  I'm using the following options:

		rsize=512,wsize=512,timeo=100

The performance is still bad, but a bit better.  Is there more I can do?
Or, should these numbers be adjusted even further?
