Straightforward numerical computations really isn't a good jit benchmark, because numerical computations are by far the easiest thing to JIT, and JITted perfs are going to be much closer to AOT than in the general case (unless the problem can be vectorized an the AOT compiler is vectorizing, I don't think JITs can usually vectorize)

Yup...I wanted to try to quickly measure just how good the JIT was for that kind of stuff, to see if we were getting to the point where it's feasible to do physics in the browser. Turns out it's "fast enough", and yet still 5x slower than equivalent stock C.
