I doubt that it actually runs JS four orders of magnitude faster. It may run JS 2-5 times faster, but 10,000 faster is very unlikely. I'd love to run some tests

I doubt that it actually runs JS four orders of magnitude faster. It may run JS 2-5 times faster, but 10,000 faster is very unlikely. I'd love to run some tests though -- is there a silverlight demo with a eval loop somewhere? (something I can type js into and see how fast it runs)
