Just to point out... OSX prefers SMB compared to NFS.

It used to be the other way around, but OSX Finder has had issues
with NFS for years.  And Apple decided to go "all-in" with their
SMB support.  The result these days is although both function "ok",
SMB functions better. :)

That being said... I've not pushed it hard personally. ;)

I just mount my FreeNAS server (which is sharing via CIFS) in OSX


In OSX 10.9.5 it's a bit slow to mount (30-40 seconds).  For OSX
10.10, it's very fast.  Around 5 seconds normally.

No idea if that's a helpful thought or not though. ;)
