Depending on what they are doing behind the scenes to create the the typed array, it could be that the only real performance benefit will occur when you use primitives.

In my opinion it's a "typed" array, or like a Generic, and so my conclusio was to test if an object-access to a Vector is faster than it is with an Array. Array -> non-typed, has to be checked at runtime Vector -> typed, faster, no check for type I am happy enough, that i have a field which is typed now, but there was this little abstract about performance and Vector in the docs ;) @jd: To be honest, i have no idea what is the right test for the “Vector”.

I don't have non-public info on the vector type myself, but from reading it assumed it enabled a more parallel-like processing of data. But the references to it in the docs were oblique enough that I suspect we'll know much more by time of final release. Glad it piqued your interest, though. ;-) cu, jd/adobe I’m not sure that an access call or a screen write would be the thing to benchmark here.

Are there any compiler-tags to produce release/environment swf for Flex? I have used a nightly build of the SDK from this week and compile it with "mxlmc VectorSpeedFP10Test.as" I simply followed the instructions from the Adobe Flex SDK Wiki to compile.
