Capturing client stats (browser rendering) through load runner
I think load runner don't capture browser rendering stats. Is there any way to capture those by using normal vuser script.
GUI Virtual User
Login_GUI-Login_HTTP = Time spent in browser processing including rendering independent of other browser processing
If you find a problem with the rendering engine in IE, Chrome, Firefox, Opera, Safari, ... what is your reconciliation path to cite a defect to the appropriate authority, track it to resolution and have it incorporated neatly into your project plan, "Microsoft, I find that IE is rendering the site 250000 microseconds slower than Chrome. I need for you to fix this by our deployment on Tuesday, OK?"
The reality is that the time required to "render," as well as the general performance of your browser is governed by dozens of variables outside of your control from the type of computer, to the OS, to the amount of resources free, to the number of other apps running on the host, to the number of toolbars installed in the browser, etc... The best you can hope to do is take a controlled instance of your application GUI in a controlled environment and look at how it performs. If you want the maximal out of tolerance condition and then pick one of the worst definition pieces of hardware in your enterprise with the oldest OS with the sparsest resource set (RAM, DISK, NETWORK, CPU) with the maximal number of toolbars installed from your user set and the run a GUI Virtual user. If you want you can compare that to another GUI Virtual user on a "Reference Recommended Good Environment" to see what difference the environment definition makes to end user performance independent of the definition of the site.

Thanks James for your reply. You have given some good points on this. Can you also please guide for configuring "GUI Virtual User", and how to run the tests on it. Do our existing Vuser scripts work on it, and will it be tested with single user or multiple user.
Adding License point:
Running GUI vuser will need a different license for 'GUI Vuser'.
