cache.html size in gwt and Slow-Loading

in my GWT project when I tested it by firebug I开发者_如何学Python saw the ...cache.html file size is very big (about 700KB) and it cause for slow-loading the project for first time. In my project it can be a problem.

how to prevent size for cache.html in GWT?

1. Use Code Splitting to only load what's needed as it's needed.
2. Use Compile Reports to find out which of your dependencies is causing your code size to be so huge, and (re)move them from the initial download.
