Re: Measure CPW used

iNav / Management Central/ Monitors has something called
"transaction rate" but I can't figure if they relate to CPW.

Rob, transaction rate is interactive transactions .... the number
of times someone at a 5250 "device" hits a key that causes the
5250 "device" to go input inhibited and use CPU/memory.

This could relate to CPW, but only for your interactive CPW
feature on older hardware.

CPW is simply a relative performance measurement to make it
easier to compare 2 different systems. Just like rPerf is used
for AIX workload.

If system1 is 1000 CPW and system2 is 2000 CPW, and neither
system has bottlenecks in memory, disk, etc. then system 2
literally has twice the computing capability of system1. CPW
tells nothing about the CPU utilization.
