Performance boost 10-16%

llafuente commented 10 years ago

Hi,

I'm writting a 2d math library: js-2dmath to do a real test, I choose to rewrite some of your code (cpVec2 atm) and use mine. The speed boost was so good... I'm really happy but...

There is a problem, js-2dmath use arrays and Chipmunk-js objects/prototypes. So before PR and cleanup are you really interested ? it's a hard change.

Another possibility is to use falafel to rewrite the code, dont know if it's really possible...

These are my numbers

Firefox (10%)

normal: "time to beat: " 18642.66666666667
js-2dmath: "time to beat: " 16883.666666666668

Chrome (16%)

normal: time to beat: 42554
js-2dmath: time to beat: 36557.66666666667

Test my fork with

git clone https://github.com/llafuente/Chipmunk-js
cd Chipmunk-js && npm install
firefox benchmark/bench.html

Oh sorry I totally missed this. I haven't touched chipmunkjs in years.

Nice performance jump! Wonder if it still holds
