[ Firefox 3.6.4 ] Poor performance in path tracing example (using WebWorkers)

Hi,

I recently came across an implementation of path tracing in
javascript, using web workers. Since the developer himself said
performance was noticeably better in Chrome, I tried FF3.6.4 beta and
Chrome 4.1.249.1064 (45376) and Chrome is at least 10 times faster (on
an Intel E8500 CPU, 2GB RAM, but I don't think this is relevant) ...

It may be caused by poor tracing in FF (JaegerMonkey would thus kick
in and close the gap), but in case it's not, here is the URL :

Hope that helps,


Matthieu.
