Everyone's job mix is unique. In our case, we found the above to be primarily
due to disk i/o, especially if using DEC's standard-issue RZ55 disk. DEC hel-
ped that some with a PROM upgrade.
We improved the situation quite a bit by adding memory - and buying third-
party disks (tho the RZ56 and RZ57 are also more competent, expensive as
well).
