One of the features of IntelliJ 7 is supposed to be faster load times but it seems like it actually got slower for me with a project with 4000+ classes. The "Loading Files" dialog flashes probably 50 or 60 times before everything finally comes up. I timed it from startup to where my project was loaded enough to do anything (with nothing else running), and it took 2 minutes, 42 seconds. Does that sound like a normal amount of time to load?
