This is a Flash10 porting of AObench.
Mr.Syoyo the author of original "AObench" already ports it on Flash10 here, and he summarized that the Flash10 is 7 times slower than Proce55ing in this entry. But I beleave that there are not such a large difference between JavaVM and FlashPlayer10, because I am an ActionScript3 Coder!!
As the result of my Flash10 porting (with some optimizations), ...
Proce55ing version; 11.412[sec]
ActionScript3 version; 10.641[sec]
And now FlashPlayer10 renders it as same speed as Proce55ing does.
Dont be afraid to execute complex numarical calculations on ActionScript3 ;)
