hi, Javascript in chrome is very fast and optimized.
Python is very slow in comparison... the python developers haven't really sped it up enough (yet). However I think, and hope that it will get better soon. Have you tried using psyco? That generally speeds up particle systems. Psyco version 2.0 is out recently which is better than the old 1.6. http://groups.google.com/group/comp.lang.python.announce/browse_thread/thread/446e7beca1f5692b however the webpage hasn't been updated properly to say it exists, or that it's hosted on a different svn. A pygame sprite demo in software gets 47fps with 1000 sprites on my laptop, with psyco. Without it, it gets 22fps or so. python -m pygame.examples.testsprite -psyco -FastRenderGroup 1000 I had good luck with a numpy based particle system. Note, use v1.3 since before that there are bugs which make writing particle systems harder (records don't work as well). GPU particle systems are the way to go for best speed of course... in which case you'll be using GLSL/etc instead, not javascript or python.
