Caputring the 'rendering' time of a page

[Ian Holsman]

Hi.

I'm trying to get winEmbed going so that I can time how long it takes 
for a page to render (display the page above the "fold").

I've seen the MOZ_REFLOW_PERF flag, which is very close, I think, to 
what I am after. Is there a better way to capture the time.


The reason why I want to do this, is that the site designers of our 
site, can have a way to measure and track different speed optimizations
of their pages.

TIA

Ian
