Discussion about official Mozilla Firefox builds
We wont see a performance boost, because the AWFY page uses Firefox builds witch already contain TI.
http://arewefastyet.com/?a=b&view=regress does, http://arewefastyet.com/ doesn't.
where did u see a boost on http://www.arewefastyet.com/?a=b&view=regress&runs=300 ???
i only see regressions since middle of august
That will come with the implementation of incremental and generational GC.
Finally something happening!
Here is what I'm seeing (compared to two days ago): V8 improved from 4109 to 4607, Kraken improved from 5351.2 ms to 4573.1 ms and Sunspider also went down from 258 ms to 246.3 ms. Nice. But Peacekeaper took a turn for the worse I'm afraid: the score went down from 5241 to 4671.
There are also regressions in some of the subtests in Kraken and V8 but I don't got the numbers.
Oh well, at least things are moving again.
I think the about:config pref for TI should contain the word "jit". In that case, you can search for "jit", and all JS engine prefs come up.
I remember some dev suggested the same for profiling. Guys, do you think it worths opening a bug?
Make sure you guys are testing the latest version of V8 (version 6) when comparing inference on/off
Sunspider: 232.4ms +/- 0.9%
Kraken: 3961.6ms +/- 0.6%
javscript.options.typeinference set to false:
260.1ms +/- 2.0%
5322.7ms +/- 0.4%
Seems like there's a performance regression for http://bellard.org/jslinux/
It used to boot up in 6 seconds. Now with TI it boots up in 13 seconds.
EDIT: Found bug https://bugzilla.mozilla.org/show_bug.cgi?id=670885
They removed the 'old' engines from the regression page
Is TI graph is in actual (JM+TI) graph? or JM+TI will be added later?
Anyone know when is Incremental GC landing? It seems to be read and finished
But dont know what is stopping it to land.
They also removed the 'old' engines from the regular page and didn't replace it with TI...
