Not to disagree but I still would love to see SMF 113 (and other instrumentation) from around a, what shall we call it?, "episode" :-) .I think the footprints in the sand will be interesting.
But I think we digress quite a long way from OOCoD.

Remember, this refers to the 'speed' of bringing down/up of the OS and sub-systems. This is done by ACTIVATING ADDITIONAL capacity and not by changing the GHz of the processor. </snip> If you are referring to the "speed boost", that is not correct. The "speed" within "speed boost" does not refer to the speed of bringing down/up anything. It does not refer to activating additional capacity (such activation is part of the "zIIP boost" AKA the "zIIP capacity boost"). It does not refer to (and does not have anything to do with) the cycle frequency, which you may think of as the GHz of the processor. It refers to the effective speed of the processor by moving it from sub-capacity to full capacity for the duration of the boost. The fact that the cycle frequency of the machine does not change to accomplish the speed boost is a reason that the boost is not called "frequency boost".
