Presenter: Scott Chapman
Measuring CPU consumption is a critical piece of both performance analysis and capacity planning. There are lots of different ways that CPU consumption can be expressed such as CPU Seconds, MIPS, MSUs, Service Units and still more. If you are confused as to what these terms mean and how they relate to each other, then this session is for you. Join me for a walk through the possible z/OS CPU measurements, conversion between those measurements, and when you might use each.
