I've found that Flash Builder 4 (formerly Flex Builder) has trouble working with large projects. After a certain point, builds seem to take longer and longer. I've tried many different ways of improving build time including:

• Moving embedded resources into externally linked projects.
• Using -incremental.
• Tweaking the .ini jvm settings including memory and -server.
• Turning off automatic build (I'd prefer not to have to do this, because one of the main reasons for using an IDE is to be told about errors as you make them).
• Deleting the project and re-checking out from the repository.

While some of these may help a bit, the performance is still annoyingly slow. I feel if I knew what was taking so long I could refactor my projects to build faster.

Is there some setting that tells FlashBuilder to let me see what parts of the build process take so much time?
