I don't think it is unreasonable for the president (or any user/manager) to
some planning to solve a problem such as an ?infrequent? 2 minute response
As an extreme example, suppose that 2 minutes was to a telephone operator
to relay an immediate response to a waiting customer?
>From your statements, the 2 minute response is very abnormal to you system,
normal is less than 2 seconds. Any extreme response, not planned or expected
indicates a problem. To jump on disk or memory or any other area, without
analysis most likely will not solve the problem. Money spent & not solving
problem will create more problems for you. Bad program design, or record
can bring an 840 to it's knees, let alone a 730.

You've got OPS Nav looking at average response. You just need more detail.
What release? Do you have Performance Tools loaded?
At V4R5, this is what I've got: GO LICPGM and option 10 will display
products you have.
5769PM1    *BASE   Performance Management/400   (the free one)
5769PT1    *BASE   Performance Tools for AS/400     (the paid for licpgm)

I would suggest the quickest answer may come from the user, like "every time
I run
xxxx the system gets slow".
The free tool, PM1, has some basic commands STRPFRMON, ENDPFRMON
DSPPFRDTA, and a bunch of reports. I do like the detail in the PT1 product.
For the long term, I run the pfrmon regularly, and look for problems.
I suspect you will find your problem, and will be able to plan to control
At a previous customer, our performance plan was based on both expected
average response, and a "not to exceed" response time. Peak work days, month
anything out of the oridinary had to be accounted for. The goal was always
that users
should never have to wait, and that is not unreasonable!. And I would expect
for green screen, client/server, lan, wan, web.

btw-current customer today, working on fixing "old" code for performance,
a 10 minute batch job, 30 times a day into 1 second each(the right access
Feels great! (am not a performance guru, but had to deal with a lot of
