Well, the need is more pressing now, but so is the desire to maintain VAX performance (ie, more users now). What performance change have others noticed after installing NFS? Name caching sounds very hard to do in a distributed system; ie, hard to keep the cache consistent with the remote filesystems. Thanks, Ron Stanonik stanonik@nprdc.arpa
