From the 1.4M page:

"On my OsX toy the difference between flash on browser and standalone is insane. 200 000-300 000 particles is pretty much the maximum until it won’t run smooth anymore. I wonder if this is memory related thing? or what? Who knows? Someone from Adobe might… Well anyways. Here’s the same thing exploding 1.4 million particles in 1920×1200 resolution with smooth 60fps."

Interesting behavior.

On that other JS demo mentioned in a sibling comment my puny 9400m runs at a steady 30fps at 100k with 7~10% CPU on Safari. The same goes for some non-browser pyopencl [0], which uses about 10% CPU. I seem to be hitting a sort of bottleneck here as ramping either up to 200k or using the Flash realtime demo brings FPS down to about the same level. The Flash one though, uses between 20 and 60% CPU and mostly hovers around 30%. Whatever that means.
