Here's my fstab line from one of my clients:
foo:/raid_local /raid nfs
rw,hard,intr,rsize=65536,wsize=65536,nfsvers=3,tcp,async 0 0
You'll note that I use TCP and a very large block size - it worked
better for me. I also run async (this is against best-practices
suggestions - use at your own risk). Note that sync is the default, but
it is slow.
Also- if you do interative performance testing tuning, you'll want to
flush your caches between runs. You can flush the NFS cache by
unmounting and remounting at the client. This may also be useful:
Good luck. It took me a while to get NFS running acceptably.
