Are there any more precise measurements?
I don't know how useful it is, but recently I helped a client build some
JS-based, in-browser page load performance monitoring. It tracks various
rendering events of a chosen percentage of pageviews. The only
server-side code processes web server logs in batch, so it is pretty low
impact, and works with cached pages. It's been served in a few hundred
million pageviews with no obvious problems yet.
I think most of the server-side code is pretty particular to their
needs, but if somebody wants it for Wikipedia, I'm sure they'd be
willing to give up the client-side stuff and my rough-and-ready initial
pass at the log parsing, which is in Ruby. If that's useful, let me know
off-list and I'll ask 'em for permission.
