Question: What PERFORM parameter in EXEC statement is meant for?

Answer: In os/390 installation, the system programmer defines several performance groups, which has specific performance characteristics like storage,speed etc. Now,each job class is associated with a default performance group. If one wants to override the default performance group associated with the class he can do it by this parameter- PERFORM=value in the JOB or EXEC stmt. When used in EXEC stmt only that step will be influenced by that performance group.
