Framerate and cpu load would be interesting informations for application developers.

Framerate display can be enabled with "layers.acceleration.draw-fps" but it only works on OpenGL (not Windows) as far as I know

See bugs 612407 and 780467

Yes, and we also have window.mozPaintCount that could be used in a more generic manner.

we actually have an addon that makes use of this.

It would be pretty easy to turn this into a shipping feature. Not sure where we'd put it, but I'd like to see it on our Developer Toolbar.

I'm moving this into the profiler. We'd like to capture framerates during profiles and display them alongside the stackdepth as well.

Comment 5

[Rob Campbell [:rc] (:robcee)]

We should open a separate bug to display CPU levels since we don't have easy access to that, afaik. framerates we will do.

tagging this so the b2g perf team can track this work.
