How to speed up the gwt 2.6 Super Dev Mode compiler?

I am updating my GWT project to version 2.6 Release Candidate 1 (GWT 2.6 RC1) and trying the new Super Dev mode .

I am using regular dev: mode in my gwt.xml:

 <!-- i compile just for Chrome -->
 <set-property name="user.agent" value="safari"/>

 <!-- with one languge -->
 <extend-property name="locale" values="en_UK" ></extend-property>

Unfortunately, I spend 3min of my life on each compiler, which can be about 3 hours a day: s, my hair begins to shed bcs!

Are all the old regular compiler optimizers still the same in the new Super dev mode, or are there some new ones for the new compiler that can do this faster?

I will be grateful for all the ideas and suggestions.

I use: hibernate 4, spring DAO, GWT 2.6, 50 tables and over 100 views
