 Zimbra is not a Java GUI. It's asynchronous JavaScript+DHTML+CSS (the 
user interface is drawn from javascript code instead of specified in hard 
HTML.)    
     
 It apparently has a Java Servlets backend, if what IG's saying is true. 
In my experience, well-written servlets deployed on reasonable hardware 
are every bit as fast as, say, PHP, and much more maintainable.    
   
   
 It is possible to severely compromise performance in servlets, of course; 
the most common way to do this is to misuse EJB.
