Load on which end? I dump all filesystems on 4 servers to the -stable
box out of daily.local (thus simultaneously), which should swamp the NFS
server fairly regularly. 14 out of 16 of my nfsd's show significant CPU
usage, considering that my uptime is 11 days (my last -stable upgrade).

I'm now somewhat nervous about the setup if you meant load on the NFS
server rather than the sparc64 client :-)
