Working on optimization can be fun, repetitive and mostly painful toward the end.
Here is my benchmark for the sort() function. I wanted to compare Array and Vector performances.
This randomizing function has been use as sorting function
test.sort(function(){return Math.floor(Math.random()*3)-1});
Data type
The datatype used for filling the vector/array : int
Loop style
1m = for(n:int=0; n<1000000; ++n)
2.5m = for(n:int=0; n<2500000; ++n)
