Did you actually compare memory usage of an JVM instance with 3.3.2 with 
5.5.14/APR (using APR and AJP will make the thread count much lower 
which should save you a decent amount of memory - see the appropriate 
parameters for the connector) ?

As for faster start, sorry, there is not much that can be done: the spec 
requires a lot of stuff now, and modern webapps actually tend to do much 
more than Tomcat itself.
