Start by reading nfsv4(4). There are also threads about people seeing immensely decreased performance with NFSv4. Not sure if Rick has had the time to fully rectify this (don't let the Subject line fool you): http://lists.freebsd.org/pipermail/freebsd-fs/2011-September/012381.html You can also Google for "nfsv4 freebsd performance" and take in what you can, but remember, YMMV. You should always test in your own environments, as pretty much everyone's equipment and setups are different. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Mountain View, CA, US | | Making life hard for others since 1977.
