Some years ago, there was a chart shown, that showed knees for the number of CPUs that MVS, VM, & VSE could handle.
Some time later, after certain updates and changes, a new chart was produced showing a new set of knees. Prior to this, Amdahl had put out the Multiple Domain Facility, after finding that there were more CPU cycles available than a single MVS could handle/manage. Is this still the case? With a Domain (LPAR to you IBM types) being able to have more than 2GB of C-Store, which reduces paging, but increases locality of reference delays, does one get max performance without 2 or more Domains running z/OS? This is strictly a CPU utilization via dispatcher question (engineering type of thing) and not a billing for software, and so forth.
