Do you have any Linux clients to test with? That way you could determine whether the problem is on the server or the client side. ISTR hearing bad things about Apple's NFS implementation (shocking, I know). You also want to test with larger files (at least 2x RAM of the server or client, whichever is larger) to make sure you're not just seeing cache effects.
---- 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/

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
