Firefox 3.1 to see speed bump with TraceMonkey

updated 09:30 pm EDT, Mon August 25, 2008

TraceMonkey adds speed

Firefox developers have been working on a new project, labeled TraceMonkey, that is poised to push JavaScript speeds even faster, according to team member Mike Shaver. By including improved JavaScript engines, most browsers have seen significant performance gains. Speed of certain processes in Firefox jumped two or three fold just between v2.x and v3.x. The new project, although new, has shown increases of 20 percent over v2.x already.

Shaver explained the goal of the project "is to take JavaScript performance to another level, where instead of competing against other interpreters, we start to compete against native code." Commands such as "for loop" are running very close to speeds only attainable through unoptimized GCC. TraceMonkey has been added to the FF 3.1 development tree.

Some of the tested benchmarks included Sunspider (and its "ubench" test), image manipulation demo, and Sylvester 3D matrix multiplication, all comparing TraceMonkey to FF3. The results ranged from being around 80 percent faster for the first Sunspider test to an amazing 22 fold increase in speed for the ubench test.

Mike noted the room for even more improvement in each category by developing "better code generation, more efficient guards, improvements to some data structures, parallel compilation, use of specific processor features, new optimization passes, tracing more code patterns, and many more." Performance across the board will increase steadily through FireFox 3.1 and future releases.

    are all these stories...

    just to try to get some of the high ground back from Safari, which announced a similar speedup months ago?

    more than speed

    I prefer the UI of Firefox over any other browser, even without any speed increase. I am just too use to where all the menus and key shortcuts are.

    Re: are all these stories

    Yes they are. Because you know the Firefox team is just so scared of Safari's 3% market share that they'll do anything to get back the limelight.

    It certainly couldn't be due to the fact they're improving their browser, one of the developers blogged about it, and someone decided to write an article on Electronista about it.

    Re: more than speed

    I use safari on the mac, but prefer firefox on windows. Not only is the interface at least standard, it has add-ins, which safari/win lacks.

    I can't surf without my blockers of annoying ads.
