Its been a long time, but I seem to remember that IBM had a computer model that the marketing people used. You could take performance data from your system and then plug in different changes, such as increasing real memory size, additional channels, additional processors, etc. and it would predict the performance improvement. I don't remember all the details. It may have been specific to MVS, since I think it used RMF data as a baseline.

Mhz is something the people being presented to understand. It does not compare to the same speed on say INTEL.

Since that number would be meaningless, no. I mean, you might find one floating about out there as a factoid, but it has zero value. Why do you care? (Reference recent discussion in IBM-MAIN.)
