  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).
