That's certainly true for the NFS part of the NFS fileserver, but to get the ZFS feature-set, you trade off cycles and memory. If we investigate this a bit, we should be able to figure out a rule of thumb for how little memory we need for an NFS->home-directories workload without cutting into performance. --dave -- David Collier-Brown | Always do right.
