How much did the elapsed time change? I find it hard to believe that the job actually ran 22 x longer and that wasn't notable as a difference.

I'm a little reluctant to run a job that already takes 12 CPU-minutes with RPTSTG(ON), but I may be able to cut the test data back significantly and still see the relative increase, in which case this may be very useful. I'll read through that tuning document as well! -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Kirk Wolf Sent: Monday, July 24, 2017 2:45 PM To: [email protected] Subject: Re: REGION=0M leads to CPU through the roof Running both with RPTSTG(ON) may provide insight.
