Appendix G. Sample performance data

This appendix contains the relative costs of a subset of the CICS® application program interface (API) calls. The information is divided into the following sections:

Using the tables in this appendix, you can compare the relative processing times of particular CICS API calls, and examine some of the other factors that affect overall processing times. These tables can help you make decisions concerning application design when you are considering performance. To calculate a time for a transaction, find the entries appropriate to your installation and application, and add their values together.

Before you work with these numbers, please note the following:
