SAP Workload Analysis: Average Response Time per Dialog Step (ms)

Response time per dialog step

The response time of a dialog step is the time required for requesting the dialog from the dispatcher work process to the processing of the dialog through the ending of the dialog in the dispatcher and the transfer of the data to the presentation server.

This also includes the time used for "Roundtrips" to transfer data from the SAP R/3 frontend to the application server and back. This time is recorded as roll wait time on the application server, while it is displayed as GUI time on the frontend. For inefficient networks, such as WAN connections, this time can contribute significantly to the response time, although it uses no resources on the application server, as the context is rolled out and the work process is released.

The response time is usually split into wait time and "dispatched" time. The SAP response time is made up of the following components:

Response time = wait time + "dispatched" time

"Dispatched" time

= Generation times during the runtime

+ Load times for programs, screens, and GUI interfaces

+ Roll times for rolling in work data

+ ABAP processing times

+ Database time

+ Enqueue time for logical SAP locks

+ Roll wait time (not including task types RFC/CPIC/ALE).

The CPU time is not an additive component of the response time, but rather the sum of the CPU time used by the individual components. The CPU time is an independent additional piece of response time information.
