+1 on this. Performance definitely needs to be addressed on Flex. I've noticed that on newer
devices, it works fine. But on the slightly older ones, performance is a huge issue. Hopefully
we can get in there and clean it up so it performs better.

(It is even worse with Flex 4 then it was with Flex 3). When a Flex application gets really
large the UI is blocked because there is too much actionscript code needed to get things running.
(with this I mean the processing time is acceptable but UI is blocked so the perception is
that things are slow)

so new and existing applications can benefit. Flex 4 with spark is great but comes with some
performance drawbacks, I hope we can improve on this significantly.

can cause performance drawbacks in large applications
