title: Nape vs Box2d ( Actionscript 3 physics engines )
body: <p>I've been testing performance of the <a href="http://code.google.com/p/nape/" rel="nofollow">Nape</a> physics engine vs the Box2D <a href="http://box2dflash.sourceforge.net/" rel="nofollow">AS3</a> and <a href="http://www.sideroller.com/wck/" rel="nofollow">Alchemy</a> ports and it seems like Nape is a lot slower than both of them. I have read in a few places( <a href="http://trentsterling.wordpress.com/2011/03/28/nape-physics-engine/" rel="nofollow">here</a> and <a href="http://www.box2d.org/forum/viewtopic.php?f=19&amp;t=6111" rel="nofollow">here</a> ) that it is supposed to be faster. Has anyone done testing between the two and if so what were your results?</p>
