This benchmark measures how fast it is to do 2D transformation matrix math in JavaScript and tells how many matrix ops your browser can do per frame. (Allocated JS time per frame being 15ms, assuming 30fps with the remaining 18ms used by drawing, scene update and scene traversal.)

Running the benchmark takes around 10s on Firefox 2 on a Core 2. YMMV.

For comparison, a 100€ graphics card can do a couple dozen million matrix multiplications in 15ms.
