A few months ago I went to a presentation where the speaker said one reason to switch to Flex 4 right away was that the compiler was way faster. I'm not seeing that at all, I'm seeing it slower than Flex 3.
I have 3 projects. One is a "flex project" and the other two are "flex library project". The main one references the other two. Whenever I have a compile error in a source file, the GUI shows 3 copies of the same error message. I'm wondering if maybe things are somehow getting compiled 3 times and that's why it's so slow.
Also I tried the solution mentioned in this article but I don't think it helped.
