Firefox 3.6.5 3x Faster with html5.enable=True

with 3 comments

Interesting update to the Firefox Speed Test feature I did a while back.

In Firefox 3.6.5 if you set html5.enable to true via about:config then you get some inpressive gains on the test case load times.

Down to 13 seconds from 37 seconds!

Wow way to go guys :-)

Note: Filter time obviously haven’t moved as this is a parser replacement nothing to do with js,

Firefox 4: the HTML5 parser – inline SVG, speed and more

@jpvincent, It’s highly unlikely that this would get backported to 3.6.x.

@jng, Flipping the pref in Firefox 3.6.x exposes you to known bugs inlcuding crashers. The snapshot of the parser in 3.6 is from June 2009 before the parser had had any testing by our community of users of nightly builds. I recommend getting a trunk nightly if you want to run the HTML5 parser and not enabling it on 3.6.x.
