Have you compared reports from SMF with what you see in the JOBLOG?  Have you 
verified with SAS+MXG or SAS+MICS or some other SMF process that can generate 
reports.  If you have a scheduling software (like CA Workload Automation aka 
ESP) it can also show your run times.  Compare those against the JOBLOG

>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.

>We have opened a PMR with IBM, but I thought I would see if anyone else has 
>observed anything like this when migrating from z/os v1.11 to v1.13, or may 
>have some idea where to look for an explanation.  Our service coefficients 
>have not changed.  Any comments would be welcome.
