Performance Monitor

Total amount of work process memory consumed that was calculated in the last phase of the Web Dynpro Framework.

Check whether memory consumption is OK.

Maximum memory consumption in the interaction step and the assigned memory could be significantly higher.

Total amount of memory used in the interaction step, which was calculated in the last phase of the Web Dynpro Framework.

If the page size ( Page Size) is displayed directly after the value, then the value is a multiple of the page size. See also profile parameter em/blocksize_KB: Segment Size for the Extended Memory Otherwise, the value is exact.

For SAP NetWeaver 7.10 and higher, you can activate the exact display by setting the value TRUE in the stat/high_resolution_memory profile parameter.

If the maximum memory consumption for the interaction step is considerably larger than the memory assigned, check whether there are memory problems in your application.

The memory can be larger than necessary due to the rounding off of the segment size.

Time needed for the request

Check whether there is a problem with the end-2-end time for the application. The end-2-end time is affected by the following factors:

• Browser rendering/JavaScript processing

  See also client time and response data

• Application Server ABAP CPU time

  See also server time

• Database time

  No measurement available for this

• ICM CPU time

  No measurement available for this

• Network transfer time and latency time

  No measurement available for this

AS-ABAP server CPU time calculated in the last phase of the Web Dynpro Framework.

Check whether this is a problem with the server processing time

• Database times are not included.

• The value is too high if the server has a debugging kernel

• The value is too high if the server is not optimally set up

• The value is not correct if the server has no comparison with a server reference server.

Estimated elapsed browser time measured using JavaScript

Check whether the size and setup of the Web Dynpro application conforms to Performance Guidelines.

• The times for the first page are usually not measured.

• The value is only a "pessimistic" estimation and is usually slightly above the actual value of the server used.

• The value can be too low because the PC used is usually faster than the PCs used for performance measurements.

Content of the AS-ABAP HTTP response for the user interaction

Check the values for the response. Large values for a response (for example, >300kB) can be an indicator for slow server and client times.

• The HTTP response also contains HTTP header information.

• The value can be much larger than the data set transferred from the network because the HTTP response is transferred in compressed format.
