Interview: Bruce Johnson discusses Google Web Toolkit
Watch Bruce Johnson discusses Google Web Toolkit (11 minutes).
From the interview:
You can identify things that appear polymorphic but really aren't, we call that "type tightening". Once you do that you eliminate polymorphism, you rewrite call sites and translate polymorphic dispatches into static dispatches and once you do that you can inline the code which allows you to do another iteration of other optimizations. So it is a real compiler and we've really only scratched the surface with the optimizations I mentioned and there are a lot more cool optimizations that we can do in the future. The benefit to GWT users is that all they have to do is upgrade the new version of GWT, recompile and they get a huge benefit in either size or speed or both. For example in 1.4 which is the next upcoming GWT release, a simple recompile will gain you about 20% size reduction and faster start-up time.
