The dirhash optimization is for UFS only.  It does not
affect NFS clients.  Of course, if your NFS _server_
exports any UFS file systems, it benefits from dirhash,
too.

Whether increasing the dirhash_max value will make a
difference depends on two things.  First check whether
you're actually hitting the current maximum.  If you
don't, increasing it would be pointless.  Second, if
you did hit the maximum, try to increase it and perform
some benchmarks to find out if the situation improves.
If you can't measure a difference, I recommend to go
back to the default value.

Best regards
