This makes perfect sense. All other things equal, NFS writes/local reads
will always be slower than the reverse, because the NFS writes are done
synchronously.

You might be overrunning a buffer somewhere. Just a WAG, but try setting
the NFS transfer size down from 8K to 4k or 1.5k. Not that that's a good
long-term solution.
