Can eValid accurately measure the "true render time" of an RIA application?

Yes, eValid can do that. No problem.

You simply issue a ResetTimer command, take the action you want on the RIA application, and then do a SyncOnText command followed by an ElapsedTime command.

The timer (stopwatch) is set to zero, the action on the RIA proceeds, playback is synchronized by waiting for the specified text to show up on the screen (actually in the DOM that underlies the screen), and then you pick off the time that action took.

The key point here is that timing is based on what is delivered by the RIA (e.g. AJAX) not on what you see in part as the page is delivered. In effect you have a timer loop on the synchronization step.
