Hello All:

Can you share tips for saving CPU Cycles inside the Central Version.

We are running 16.0 SP2 on Z/OS 1.7 very soon to be 1.9. We have a lot of ADS/O and a lot of DC-COBOL programs. ON Production we only do a load module migration, there is no source code.

I am aware of turning off symbol tables, what about diagnostic Tables? (Load Modules Only, in Production)

I am aware of including the Built in Functions in ADSOMAIN.

We are using the High Speed Storage Protection option, we have five storage pools, 0,1, 128,129 and 255.

We also have PREFETCH on in the central version as we have very large buffer pools, is this a big CPU eater?

Any other things that we can do to save some CPU Cycles?
