To speed up GWT compiler, the main idea is to reduce GWT permutations.

1. Force a browser

In your module.gwt.xml, force an user agent : gecko1_8 (Firefox 2).

    <!-- User Agent -->
    <set-property name="user.agent" value="gecko1_8" />

2. Use only one locale

By default, GWT use "default" locale and comment yours locales.

    <!-- GWT locale
    <extend-property name="locale" values="de_DE" />
    <extend-property name="locale" values="en_UK" />
    <extend-property name="locale" values="fr_FR" />
    <extend-property name="locale" values="hr_HR" />
    <extend-property name="locale" values="hu_HU" />
    <extend-property name="locale" values="it_IT" />
    <extend-property name="locale" values="pt_PT" />
    <extend-property name="locale" values="pl_PL" />
    <extend-property name="locale" values="nl_NL" />
     -->

With this two points, GWT really speeds up but i can improve this.
