Regression testing

One of the primary objectives of testing the performance of the CICS TS product is to ensure that workloads do not observe a degradation in performance when you upgrade to a new release. The process of comparing one release of CICS TS with another by using identical workloads and identical configurations is known as regression testing.

Each of the performance reports relates to one release of CICS TS. A significant component of the release-specific information is the result of running regression test workloads. For details about the workload results, see the reports for each release of CICS TS:

CICS TS V5.1 performance report
CICS TS V5.2 performance report
CICS TS V5.3 performance report
CICS TS V5.4 performance report
CICS TS V5.5 performance report

Many workloads are using during regression testing. Some of the workloads that are available to the IBM CICS Performance Team are shown in this report.
