As you have decided to map your entire db in ram, you'll hardly benefit
of load-balancing, except if ou had designed a n tier model :
browser <-> apache <-> jserv <-> data cache <-> rdbms
where "data cache" could be rmi/corba server, EJB server or java space
(he he !), or rdbms !
So now you are only vertically scalable. Unfortunately green thread JVMs
will not fully benefit of MP hardware.
