How to get the time when the first screen is finish?

[Chuanwen Wu]

Hi all,

I want to do some analysis work about the first screen.
First screen(or first page), I not sure whether this name is
appropriate, is the screen we see when we open a webpage without
scrolling down. I mean a webpage maybe have many content and be
composed of more than one screen, and we need to scroll down to read
the content in the other screen(except the first screen).

I think from the perspective of the user experience, the performance
of first screen is more important than the rest. So I want analysis
about the performance of the first screen.

To analyse the first screen, I need to get all the components which
are received (maybe and render) before the first screen is showed to
the user.
Now, my problem is how to judge when the rendering of the first screen
is completely?
Maybe this would need to listen to the paint even. So, the problem
maybe is how to listen to the paint even and detect what happen?

Any help will be very appreciated!

The solution would be better if it can support both Firefox-3.0.x and above.

You can try Firebug Paint Events 0.1.6, that displays details of
MozAfterPaint events
(you need Firefox 3.1b1 min)

Hi,
Thanks!

As I know Firefox-3.1 and the above have a feature "worker threads",
which can download the JS file in parallel. But now many other browser
still can't do this. I want to create a plugin to give some webpage
optimized advice, which I hope can be use in most browser.
So, is there any way to disable the feature that download JS file in
parallel in Firefox-3.1x and above?

You will have to ask Firefox about that.

Because MozAfterPaint don't support Firefox-3.0.x, so except
MozAfterPaint, is there any other way that can be use in firefox-3.0.x
to listen to the paint events?

I don't know about any workaround for this.
