Sometime ago we obtained NFS from XINU for our VAX 780
running 4.3bsd, but we didn't immediately install it
because the need wasn't pressing, and we'd heard that
NFS's lack of namei caching (or something analogous
to it . . . namev caching?) was a big (~20%) performance
loss.

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,
