As has been pointed out, there are many IBM tools such as zPCR that you can download to help with this exercise. The tools require either a good estimate or RMF data from the LPARs to give you an accurate comparison. In running one job anything can happen to distort the figures.
However, I think a rough calculation without regard to the other work in the LPARs on the several CECs can give you an idea of what to expect. If we make the assumption that both CECs are running a similar workload....not bloody likely give the CEC's design difference, disk drives, I/O configs, WLM settings, OS version, etc....but using numbers from the latest MIPS ratings here is what you are up against: z9/722 rated at 1226 MSU z900/2C3 rated at 144 MSU I'd guess your job is going to run 1226/144 or 8 times slower. Let us know what happens. Of course if the z9 is running at 95% and the z900 at 5%, your job may be faster on the older CEC Remember, objects are always closer than they appear in the mirror, and your actual mileage will vary. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
