z/OS 1.7 to z/OS 1.9 Migration - Increase in CPU/MSU Consumption
We are just about to start the migration from z/OS 1.7 to z/OS 1.9. Would someone provide a "ballpark" percentage increase in the amount of CPU resources between the two releases so we can estimate the monthly increase in our z/OS base monthly billing?

Hi John, You *may* actually save some CPU with regards to other system related overhead associated with this upgrade. Check the MXG archives under subject Master for a thread in which a few Users are experiencing less CPU with regards to Master and RSM upgrades when migrating to z/OS 1.9.

Re: z/OS 1.7 to z/OS 1.9 Migration - Increase in CPU/MSU Consumption
To be precise, it appears that the savings are actually as a result of RSM modifications in z/OS 1.8, carried forward, not z/OS 1.9. Sorry bout that.

Re: z/OS 1.7 to z/OS 1.9 Migration - Increase in CPU/MSU Consumption
John, Marianne Hammer of IBM gave an excellent SHARE presentation that showed the changes between releases. Go to www.share.org, click on Orlando Proceedings to the left, then search for session #2530. There is first a section about going from z/OS 1.7 to 1.8, where the goal had changed from being +/- 1% of equivalency to improving the performance. The performance improvement ranged from 1.6% (low n-way) to 4.8% (high n-way). For 1.8 to 1.9, the goal was a 5% improvement and their LSPR benchmarks showed a 5.2% improvement. Your mileage may vary, so it's very important to use WSC's free tool called SoftCap (WSC PRS268), which lets you enter the breakdown of your workloads to see what your expected change will be.

It appears that comparisons and branches are being combined into single instructions on the z/10 processor. I would estimate that when z/OS, or its successor, requires a minimum of a z/10 processor, we'll see further improvements in operating system performance, and perhaps a slight improvement in storage utilization. While older version of z/os (or any other system) will PROBABLY continue to run, later versions will utilize these new instructions heavily, with improvements as each component is updated.
