Measuring rendering time

[laredotornado]

Hi,

I have the latest version of Firebug for PC Firefox. How would I use
Firebug to measure a page's rendering time? That is, the time from
immediately after the page is downloaded to the time it appears in the
browser?

Thanks, - Dave

This is currently not supported, but definitely something we would
like to have.

The plan is to put such timing information into Net panel, which
already
displays timing info about page load (the graphical representation
of page network activity called timeline). This graph utilizes mainly
on-http-request-modified (request start)
on-http-examine-response (response received)
nsIProgressListener (tracking file download progress)
DOMContentLoaded (displayed event within the timeline)
onLoad (displayed event within the timeline)

Further we would like to also display MozAfterPaint and display an
additional
info in the timeline graph about page repainting.

What event's do you think should be used to measure the time
between: (a) page is downloaded and (b) page appears in the browser?
