Response Time ysis of Web Tem tes Prerequisites To generate trace files that are required for the detailed performance ysis you need to download and unpack the file IEMon.zip. This file can be found at  Performance. Frontend Response Time ysis For the frontend response time ysis the IEMon.exe tool is used. This tool is a simplified Web browser with enhanced HTTP protocol logging facilities. While executing an HTTP request the tool logs all outgoing and oming protocol messages and other browser events, together with a millisecond based time stamp, into a log file. From this log it is possible to extract the tim ween sending an HTTP request and receiving the HTML response, and the time required by the browser to render this HTML response. Both times together are perceived as response time by user. Backend Response Time ysis For the backend response time ysis we rely on the contents of ABAP runtime traces. In the context of Web reporting, the ABAP trace needs to be activated whenever a HTTP request arrives at the corresponding service handler. This is done within transaction SICF (see detailed description below). As ABAP tracing always has significant impact on the response time, we recommend creating the frontend log file and the ABAP trace files in separate executions of the query. Generation of Trace files Installation of IEMon.exe In order to use the IEMon.exe ysis tool, unpack the archive IEMon.exe into a separate directory. IEMon.exe can be e
