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. Cheers!

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?
