Transaction response time

You can calculate the internal CICS® response time by subtracting performance data field 005 (start time) from performance data field 006 (stop time).

Figure 1 shows the relationship of dispatch time, suspend time, and CPU time with the response time.
Figure 1. Response time relationships
The response time is the total time from the transaction start time, to the transaction stop time. The response time can be subdivided into two periods, the suspend time and the dispatch time. The suspend time includes the first dispatch delay, which begins at the transaction start time and ends partway into the suspend time. The suspend time also includes the dispatch wait, which begins further on into the suspend time, and ends when the suspend time ends and the dispatch time begins. The dispatch time includes the CPU time, which begins some time after the start of the dispatch time, and ends some time before the dispatch time ends.
