Flash Player performance

[kookaburra]

Adobe says that AS3 code can run 10 times faster that the legacy code Actionscript code.

What I'd like to know is Will the code written in AS1 or AS2 using Flash CS3 IDE run as fast as the AS3 code?

I don't believe you'll see an increase in performance by compiling your AS1 code in CS3. The big performance boost is in switching to the more efficient AS3 language.

its not even possible to use the as2 code in as3 ;) because some of the sintaxe changed.. so by converting to as3 you get better performance ( i think )

No AS1/AS2 code uses the old AVM1, you wont get any performance gains unless you use AS3 which uses the new AVM2.
For more information about AVM2 see http://www.adobe.com/devnet/actionscript/articles/avm2overview.pdf
