My understanding is that NFS is pretty poor in performance in general,
so I would expect it to be particularly bad for a DB.  You might run
some (non-DB) performance tests to get a feel for how bad it might me.
(Someone once told me that NFS topped out at around 12MB/s, but I don't
know if that's really true [they were trying to sell a competitive
networked filesystem]).

In any event, you're at least limited by ethernet speeds, if not more.
