Sounds like a "third bear of IMAGE" problem should be considered.

BTW, I agree with Gavin and Craig L's posts.

It looks like you need a real performance analysis.  Don't forget
the usefulness of SPT/iX, BTW.

Also, during your busy times ... what does the "speedometer" say
your CPU utilization is?  If it's less than, say, 70 or 80%,
then you're probably waiting on disk.

speedometer:
   At the hardware console, press control-B. That should start a display,
   at the bottom left of the screen, of four-digit hex numbers.
   If the system is still somewhat alive, there should be a pair of
   hex numbers alternating between FFFF and F#FF (e.g., F7FF).
   We're interested in that F#FF, not the FFFF.
   The '#' is the percent busy, divided by 10.  Thus, F5FF is 50% busy.
   And FAFF is 100% busy (hex A is 10).

Out of curiousity, what MPE/iX version were you running on your
9x7 systems?  (It clearly wasn't 7.5 ... thanks to HP Marketing)
