I received a couple of quick responses from Dr. Thomas Blinn, and Blake
Roberts. Thanks for you responses.
They both reconfirmed what I already knew. I can't do much more on this box,
and more performance is obtainable via a faster cpu.

You're 100% (effectively) compute bound; you're not paging, you are using
about 95% of the CPU in "user" and perhaps 5% in system activity (which
you can't readily change).
You need a faster CPU. I doubt you can get one in a DS10 box.

Hi Mike,
Personally, to me, the system looks like it's performing like it should,
since it's only running one application. You are not memory bound, and the
application is using the vast majority of the CPU time (high User load, low
system load). This is all very good. The only thing that would indicate to
me if you're really CPU bound is if you have high load averages (>5.0),
and/or there is lag when you're typing commands.
I do not know if Compaq is going to come out with faster CPU's for the DS
series. If they do, an upgrade is possible... but I would look at your load
average during busy periods, and keep trending what you're doing, before I'd
look at making a hardware purchase.
Best regards,
