I'm interested in speeding things up.  Maybe you would be so kind as to 
post a brief summary here and on the sourceforge site explaining what it 
does and how it works.

Things I have tried to varying degrees of success:

* Buy faster hardware :)

* Make use of cachable hbm.xml files in projects that have the hbm.xml 
file in the WEB-INF/classes directory, but sometime this is not possible 
as hbm.xml are inside JARs.

* Make web-app ServletContextListener.contextInitialized() create a 
background thread which creates the SessionFactory and once ready it 
calls a notify callback chain to kickstart Session users.

* Use a separate web-app to build and keep the SessionFactory, so that 
the web-app you are developing can be reloaded independently.  This is a 
little like JBoss AS hbm service (forgotten what its called) but for Tomcat.
