I have not run the system yet, and I am not in this area anymore, but as a general hint of what might be interesting here is some info from when I was doing performance analysis. I had a set of 'TOP 10' reports that included:
By job CPU time - individually
by job cpu time - total for all runs
by program CPU time - individually
by program CPU time - total for all runs
by CICS transaction - total for all
by CICS transaction - average for transaction
by DB2 plan - total for all
by DB2 plan - average for plan
The CICS and DB2 reports were given for elapsed and CPU time both.
These reports allowed me to focus on the areas that were 'costing' the most and decide where to drill down and make improvements. Once we got what we could out of an area, I added it to a list to exclude. Once in a while I would run the reports without the exclusion list just to see if things had changed.
