Very useful video. One question, and my apologies if you addressed this and I missed it: what are the performance implications of building against the Flex 2 framework? I remember you saying that building against the Flex 2 framework will cause it to use the Flex 2 compilers instead of the Flex 3 ones. Does that mean giving up some of the performance improvements in FB3?

David,

That’s correct — specifying that your project uses Flex 2 means giving up some of the performance improvements. Compiler performance improvements are implemented in the Flex 3 compiler, so when you specify that your project should compile with Flex 2, it will use the older compiler which does not have those performance improvements.
