That’s even more difficult to characterize, but (eyeballing it) 1000X must be too high.
Maybe... it's hard to find a good comparison over that length of time. But a Multiprise 2000 is in the original Pentium era.
A $1500 Lenovo boasts an Intel i7 with 8 cores/16 threads. If 8 cores gives e.g. 5x throughput, it only has to achieve 200x the single CPU speed of a 1996 Pentium for 1000x increase overall. It might not be 1000X but it must be close.
Having a zIIP gives you plenty of horsepower for z/OSMF, and having an IBM z15 gives you System Recovery Boost which gives you…plenty of horsepower for z/OSMF at least during the first 60 minutes. (It’s the z/OSMF startup that can take a long time on a low capacity configuration.
I wouldn't be surprised if once people start using z/OSMF, it's not just the startup that is slow on a small system. Maybe IBM should give everyone one zIIP with their z/OS 2.5 license... it might even be a useful stimulus for smaller z/OS sites.
