Speeding up NFS Performance

NFS has a lot of server tuning's available. It's default mount settings are very conservative, you can easily make it 6X faster just by changing the mount settings.

Alfred Perlstein suggested the following mount options, and they work great:

 nfsv3,intr,rdirplus,-r=32768,-w=32768


If you've got a real busy network, adding tcp to that list will help your performance, but udp on a clean switched network performs better. Man mount_nfs for more information

For example:

 mount -t nfs -o nfsv3,tcp,intr,rdirplus,-r=32768,-w=32768 merlin:/freebsd/misc /mnt
