IBM Z Large Systems Performance Reference

Ratios are based on measurements and analysis. The amount of analysis as compared to measurement varies with each processor. The data that follows is based solely on IBM's measurements and analysis of the processors in the tables. For machines not listed in the tables, contact the corresponding vendor for performance information.

Many factors, including but not limited to the following, can result in the variances between the ratios provided herein and actual operating environments:

• Differences between the specified workload characteristics and your operating environment
• Differences between the specified system control program and your actual system control program
• I/O constraints in your environment
• Incorrect assumptions in the analysis
• Unknown hardware defects in processors used for measurement

IBM does not guarantee that your results correspond to the ratios provided herein. This information is provided "as is", without warranty, express or implied.
