We upgraded from z/os v1.11 to v1.13 on our z10 about 2 weeks ago. Ops reported that all batch jobs are taking longer 'wall' time. Researching the cause, we Looked at job step termination stats. We discovered that, on z/os v1.13, all steps are reporting about 50 times the number of service units as were reported on z/os v1.11. While TCB & SRB cpu times seem equivalent (no dramatic increase on v1.13), the elapsed time has increased roughly by a factor of 2 and the "SERV" value is dramatically higher for each step. A job that took 30 mins now takes 75 mins. We first thought it may be a problem unique to SORT (SyncSort) but even the Control-R step (as well as non-sort steps in other jobs) is 30x higher.

A shot in the dark: Do you have the same data sets in the parmlib concatenation for both R11 and R13?
