Flex 3 : Module Optimisation

In my last post I mentioned that the must have feature for me in Flex 3 is the module optimization. So one of the first things I did this morning after installing Flex Builder 3 was to re-publish an existing project using this feature. This project uses 25 modules to manage the various elements of the system. Prior to optimization the size of the published modules was between 140 Kb and 470 Kb. After optimization the size was between 24 Kb and 180 Kb. You can do the maths on the actual percentages but however you look at it's a very significant difference for very little effort. You can see a video of Tom Lane explaining this new feature here.
