  I'm mildly doubtfull **if the server is functioning as a workstation at the
same time**.  Using somewhat slower RZ56's we found a combined
station/fileserver was not giving good performance with three disks, bud did
give good performance with a pair of Wrens.
  I didn't measure anything, so I don't know for sure what ``knee'' we hit,
but I mildly suspect total i/o's per second, based on some measurements on
non-workstation servers with three RZ56s

  Yes and no: our other configuration is one 2100 to 11 diskless clients,
and the performance problems there are strictly bottlenecks in swap i/o (not
that I would recommend diskless 2100s to my worst enemy, you understand).
There are no visible bottlenecks on the non-swap disks.
