This is a fantastic article. I did not know, haxe's optimization, but if You use: ... flash.Memory.setI32( i*4 , v[i] + 1 ); ... can it be faster with bit-operations? Like i<<2 ? Or haxe optimize this? Thanks for Your answer. Hi!

To be fair to the bitmap versions, you should eliminate the "%" operation by using two loops, or making the width a power of 2 and use the "&" operator. However, I'm sure that this will not close the gap to the memory version! Hi - interesting stuff.
