Hi all, I have migrated two Flex Builder/SDK 3.0 Projects all the way up to Flash Builder/SDK 4.5.1. One project is a library project that compiles to an RSL. The other project contains two applications that use the RSL library. Everything now seems to be compiling and running correctly in 4.5.1 but I have noticed that the RSL size is much bigger than before when I do an Export Release Build of the applications:
Flex Builder 3.0 & SDK 3.0 library SWC (in library project bin folder) : 1107KB library SWF (in applications project bin-release folder) : 507KB Flex Builder 4.5.1 & SDK 4.5.1 library SWC (in library project bin folder) : 1102KB library SWF (in applications project bin-release folder) : 977KB I always assumed that the RSL file size reduction (~50%) in Flex 3 was because the debug information was being stripped out and the library optimized as part of the Export Release Build. However this does not seem to be happening in 4.5.1. Have I missed a configuration option or something? How can I reduce the size of my release build RSL SWF in 4.5.1? Regards, Nick.
