Server Timing API

[johnbillion]

The Server Timing API will appear in Chrome stable soon.

I've already messed around with an implementation in QM but I didn't find it very useful. Maybe it needs some more thought.

Really the only thing I can think of that would make sense, is the amount of time that QM (collectors and output) adds to the document's response; would be helpful for gaining a more accurate understanding of QM's impact when evaluating a page's performance.

Perhaps QM could use #309 to time itself?

Could this be useful to measure/debug the time each plugin is taking to load? (or there another way to do that already?)

You could use QM's timing functions on plugin_loaded and plugins_loaded actions.
