170284 - Extra performance info for pageviews

Status: NEW

Description

[Bart van Bragt]

I totally loved the time display 'Done (0.12 seconds). Have used it quite a bit
while developing phpBB (www.phpbb.com). I know, it's not very accurate,
especially because it includes network/server delays but it does give you a
ballpoint figure when trying different templates/stylesheets/JS code.

I would LOVE to have some kind of time statistics. It would be ideal if I could 
see:
- Time between request and first reply from the webserver
- Transfer time (including bytes/sec)
- Time for parsing HTML
- Time for running scripts
- Time for rendering the HTML
- Time that was needed for waiting on additional page elements (i.e. images).

Would be fun if there was some kind of pref that would output above info to 
some kind of debug console or if it would be an extra tab in the 'Page Info'
dialog..

This would all be a fantastic help because one of our main goals with phpBB (and
with all my other Projects) is optimization for speed.
Thanks

confirming RFE; computing some of those times may be very difficult...

Thanks for the confirmation.

Indeed, some items are fairly non-trivial to compute but they are very usefull
on the other side..
And they can also be used for profiling the Mozilla code. Maybe this is also a
usable feature for the performance crew?

BTW I'm fairly easily satisfied.. It would already be an improvement if the
'page complete'-time would return that bug 48436 has removed.

doesn't belong in pageinfo component

->Browser General, I'm sure there's a better place though
