CLPA is used once a month (or less) during scheduled outages and the last time I checked CPU utilization on the CPC was pretty low during NIP. :-) OTOH, IEBCOPY gets executed thousands a times a day. Including prime shift / hours where CPU utilization is at or near 100% across all our CPCs. Perhaps a better comparison would be one of Ted's favorite subjects.. CPENABLE. I don't know anyone that has successfully measured the difference between (0,0) and (10,30), but yet we all set it to (10,30) now because that is what IBM recommends as best practice for less overhead. And that is my only point.. using IEBCOPY COPYMOD for all executions is not best practice where performance / CPU utilization is a concern. The numbers I posted don't lie.
