title: GWT: High resource usage during mvn goals
body: <p>I have noticed a high memory and CPU usage during mvn-gwt operation especially during compile phase. Memory usage just soars. I just wanna know if this is normal and if anyone else is experiencing this. </p>
  
  <p>My current JVM setting is <code>-Xms64m -Xmx1280m -XX:MaxPermSize=512m</code></p>
