Start Render - will my change show here?

Is it external or inline js? In general it should get a LOT faster but that's assuming the UI didn't depend on the js. The easiest way to show it is to run a test with video capture enabled of before and after and then create a side-by-side video of it (go to the test history, check the compare boxes for the tests you want to compare and hit the button).

Before doing the work an easy way to see what the payoff will look like would be to block the js files in question which will prevent them from loading and should give you a good idea.
