Hmm, async is specified in /etc/exports.  However, in my early testing I
found that there was no discernible performance difference (with
bonnie++ iirc) between setting the exports one way and setting the
client mount option instead.  Either one set to sync would cause
performance drops, as expected, but to the same degree.

I can't change either the exports or client mount options for another
month however, until our quarterly downtime.
