Hi Ed! I knew what Robert meant. The answer is NO.
We did a SNAPSHOT last year. Ran through dozens of scenarios, even tuning them on the fly and re-running them. It did not provide any benefit to our workload and, in numerous cases, actually made things worse. As usual, YMMV.

Put another way, on any given CPC (regardless of the total number of CPCs you run), do you set the number of logical CPs for any of your LPARs equal to the number of physical CPs available?
