I was using a 648 Gb 'PSD' file which surely is beyond caching.
You definitely were correct in your assertion and stupid me should have
tested it from another Linux box.
$ time cp BackgroundGraphic.psd /home/filesystems/srv-adv/
real 0m18.547s
user 0m0.015s
sys 0m3.306s
so the problem isn't NFS slow writes...it's slow NFS writes from
Macintosh client ;-(
I'll play around a bit more but it's clear that no matter what I do, NFS
writes will never be faster than AFP or SMB from a Macintosh so given
the extra pain of setup, it's never going to happen.
Thanks
Craig
