(I forgot to send this yesterday, and Jim Mulder beat me to it. The only thing he omitted was about space-switch interrupts).
>What exactly does "x% of system time" mean? >Is it a pecentage of the LPAR CP capacity? You might say it doesn't mean anything "exactly", but it does mean something "approximately" :-) Approximately, total - CPU time spent processing PER interrupts - CPU time spent processing space-switch interrupts Divide by number of online CPUs Divide by total elapsed time since trap was enabled Multiply by 100 It is quite inaccurate when you consider CPUs coming online and/or going offline, or parked logical processors, or zAAPs/zIIPs on a business class machine, or not dedicated processors.
