As Nightly 28 winds down, I would like to highlight some of the
performance gains we've made on the Tom's Hardware Guide benchmarks (Web
Browser Grand Prix aka WBGP). Though Chrome still leads overall, we've
improved our Peacekeeper and Browsermark scores and we've identified
more hotspots we can improve. :)
Here are some rough measurements (bigger is better):
Browser Peacekeeper Browsermark CanvasMark
------- ----------- ----------- ----------
Firefox 25 2756 5140 6260
Nightly 28 3289 5414 6196
Chrome 31 4278 (1.3x) 5453 (~1x) 9566 (1.5x)
We'll be tracking a number of benchmarks weekly and you can see some
prettier graphs (temporarily behind LDAP) here:

If you would like to help, here are some JS and DOM performance bugs
that would improve our benchmark scores:
* Bug 812201 - Scirra RenderPerf3 slower than Chrome [70% of time in JS]
* Bug 885514 - IM: Compile try-finally [Peacekeeper, Shumway, and JSIL]
* Bug 939115 - Optimize arr.splice with unused return value [WIP patch]
* Bug 929507 - Yarr is not compiling jQuery selector parsing regexp
* Bug 820848 - Support using LCallDOMNative with HTMLDocument methods
* Bug 932837 - Optimize JSStackFrame::CreateStack/DescribeStack
* Bug 929950 - PCToLineNumber is slow
* Bug 688219 - String.prototype.split cache
* Bug 892687 - Make returning object values not require fallible methods
* Bug 946982 - CanvasMark 2013: "Arena5 - Vectors- shadows- bitmaps-
text" test is 3.4x slower than Chrome
* Bug 946979 - CanvasMark 2013: "Asteroids - Bitmaps- shapes- text" test
is 2.4x slower than Chrome
