It is true that with reducing the # of jobs (inits) running concurrently, your CEC load is somewhat lower. Well, at least that worked for us until we upgraded our z toys.

Why? >Because if we are running below our cap, then we are "saving up" MSUs. Sort of yes, but the elapsed wall clock time of all those jobs will be somewhat shorter because of 'less overhead'. >This despite the fact that the z/OS is scheduled to die in Dec 2015. That was not the first 'die date'. When was the last 'die date' set last time? I believe you have posted an earlier date here some ages ago.
