Because browser-driven load tests use Internet Explorer for replay, you should be aware of the following: The browser (Internet Explorer) uses memory. Depending on the version of Internet Explorer that you use, this memory footprint varies. Memory usage depends on how you have configured the caching settings in Internet Explorer. The application under test uses memory, which often increases as the VUser interacts with the application. To get a basic understanding of how much memory a VUser requires when conducting a browser-driven Web load test, execute a try script run and monitor the memory usage (uncheck the Visible Client check box for exact results). Note that memory may increase while using the application under test though. It is recommended to script BrowserStart functions at certain points in your script to reset the browser state (cookies, cache and history).
