GWT Code Splitting

In my GWT + GXT project, the obfuscated javascript output file is around 1.1MB. It takes quite long for the browser to load all the files before the system is running. So I gave a look on GWT code splitting.

It's very simple and just need to implement

1. GWT.runAsync(new RunAsyncCallback() {}
2. Set GWT compiler parameter : -compileReport. Make sure you disable draft compile mode since it will not produce the SOYC(Story of your compile)
   

You can see the compile report as you know what is going to be downloaded on initial download, full download and leftover.

Soon I will try to reduce the usage of the GXT library which is the most codes included in my initial download.
