system tuning question

I am looking at these:
The system seems a bit slow in response time. Not only that, but often
there is a fairly big delay in doing something simple. Running a simple
command
like wrkobj at time this has taken 20 seconds to come up. Worse than this,
we have a very large Financial A/R report that when it runs full blast it
literally knocks people out of their screen on the Java XT side. We are
underpowered but till we improve that I want to see if we can tune.

QACTJOB *ALC Initial number of active jobs = 200
QADLACTJ *ALC Additional number of active jobs = 30
QADLTOTJ *ALC Additional number of total jobs = 30

If there are other system values to consider please tell me. Note, I am not
going to make changes on my own but only will present the findings or
advice from the experts here.
