I was using a 648 Gb 'PSD' file which surely is beyond caching.
Your initial email stated "648 Megabyte Photoshop file (PSD)". Also, your transfer times are on the order of 20 seconds. Unless you have a network running at 32 GB/s, I don't think you mean 648 GB.
As an aside, it'd be fun to watch Photoshop try to open a file over half a terabyte in size.
You definitely were correct in your assertion and stupid me should have tested it from another Linux box.

so the problem isn't NFS slow writes...it's slow NFS writes from Macintosh client ;-(
Get rid of the Macs. Problem solved. ;)
