Suppose there is a daily job that runs for 2 hours 5 minutes of CPU time, and we tune it so that it completes in 5 minutes CPU. How to showcase the benefit of 2 CPU hours savings?
In an SCRT environment where the bill to IBM is mainly based on peak 4 hour rolling average. If the CPU saved is not in the peak 4 HRA then how can we quantify the benefit, if possible.
I had a thought that "CPU not used is still CPU available for other processes to use" so there is one benefit.
Are there any other thoughts on this? Thank you

| That amount of reduced cpu time will most likely also lead to much reduced runtime, so other resources are held for a much shorter time. It also means that you have much more time to fix any runtime errrors and still be within the batch window, if you have one. |
