WPF/E vs DHTML vs Flash vs WPF performance test
Here are results I got testing with 16 [animated bouncing] balls on my Pentium M 1.7 laptop:
[...] WPF/e is much faster in IE than in Firefox, which seems equally slow for all three tests. The expected result is that WPF runs faster than anything else. The unexpected is that WPF/e is faster than Flash despite the fact that it’s been in the market for years.
Browser DHTML Flex WPF/e WPF IE 6.0 56 61 84 99 Firefox 18.104.22.168 55 52 58 - Opera 9.01 94 50 - -
Since the tests focus on a narrow animation sample, one would be cautious to put too much into the results. Regardless, the findings are very interesting. Alexey has posted sources for the tests so you can run them on your own machine.
