I'm deliberately not testing anything related to graphics, sound, input, etc. in these tests. As for test averaging, I do post the raw data for anyone interesting in seeing the individual test times or computing an alternative (eg. geometric average) total time. Let me know if you finish your port of a "standard" JavaScript benchmark. I'd be really interested in seeing those results!

The problem, knowing the "flash-bashing" situation, is to handle the result with precaution : - The bench only measure javascript vs actionscript performance, not the complete platform (flash vs html5). - It compares total time of several tests, which means that if one much slower test while other are fastest might lead to a bad global result, even if the slower test is not often used in real case. I think it might be better to use geometric average of scores, rather that sum to times. Score being ratio of test time versus time of a average configuration. I'm currently working on porting "standard" Javascript benchmark (V8, Sunspider...) but it's a long term project, and results are sometimes surprising... and hard to explain. Nice bench.

Also, note that the gap has widened further in <a href="/articles/534" rel="nofollow">followup</a> <a href="/articles/618" rel="nofollow">tests</a>.

Javascript has a much slower Runtime than as3, and even as2. If I didnot tested it for my self I could believe you. Tel me, how dose the Apple pays for this kind of a reverse marketing? this is stupid. Javascript has a much slower Runtime than as3, and even as2.
