Performance testing team is using Load Runner to measure the performance. The load runner is capturing response time for every screen (click 'NEXT' button on the screen flow). However the response time captured by Load runner varies drastically with the Server Elapsed time captured by Pega PAL. Pega PAL is reporting very low Elapsed time when compared with Load runner
Screen 1> Load Runner (3.1 s), PAL (0.18 s)
Screen 2>Load Runner (1.9 s), PAL (0.45 s)
Screen 3>Load Runner (5.87 s), PAL (2.78 s) and so on
Why there is different in elapsed time between the tools? Is there something Load runner takes into account which PAL doesn't?
