Response times

The response time percentage increase depends on the amount of application business logic and on the number of CICS®, MQ, DB2®, and IMS™ calls per task.

A task with a large amount of business logic but few CICS, MQ, DB2, and IMS calls will have a negligible response time increase. A task with a minimal amount of business logic and with many CICS, MQ, DB2, and IMS calls will have a significant response time increase.

CICS DB2 application with interdependency data collection

Internal response times showed an increase from around 24 milliseconds to 28 milliseconds, caused by the overhead of interdependency data collection for 200 SQL requests.

CICS VSAM application with interdependency data collection

Internal response times did not noticeably increase, because of the overhead of interdependency data collection for the File Control commands. The typical internal response time was 5 milliseconds.
