Hey all, Josh and I now made some speed tests with both 2D physics engines - Box2D and Chipmunk - and here are some results. One warning though: The tests were made with Python, and for Box2D there's a library compiled with swig, whereas Chipmunk's interface is done with ctypes. This may change the results to Box2D's advantage, but is justifiable as our interest right now is which performs better with Python and on the xo laptop.
In the end, Box2D performs quite a bit better than Chipmunk, although it has a ways larger library and many more functions. On a XO Laptop (build 650), the Box2D engine can easily handle 50 elements - almost twice what we got from Chipmunk. The tests capture frames per second and compare them with the number of elements - in our case we add only balls. By pressing "1", 25 balls will be added at mousepos. Each test is run with and without drawing the elements on the screen.
