Yes, Some jobs requires more CPU time than others.
This is not the problem, but analysing various factors affecting Elapsed time apart from CPU time, EXCP, Mainframe Load, database access and storage factors.
I saw this CPU% factor and misunderstood that it is Allocation factor.
Some jobs use less cpu%
Above statement made me to think that it is not the allocation factor but it is used one.
Thanks for your reply and your suggestion on alignment. I will take care.

Workload Manager (WLM) is the basic control mechanism for the system -- including CPU -- and it is possible to select individual jobs to run in certain service classes in WLM. So yes, there are ways, other than job class, to control use of the CPU. Workload management can be a very complex topic and there are manuals (and Redbooks) available to help optimize system resource usage.
However, there is nothing unusual or different about jobs in the same job class using different amount of CPU -- some jobs need more CPU time than other jobs. If you are really that concerned, talk to your site support group about the WLM policies in use at your site.
