Each server setup is unique and needs to be tuned for it's purpose, applications running and hardware. I have a couple of JVM Tuning posts on my blog that serve as a guide but not meant as an exact this is how you do it. http://www.trunkful.com/index.cfm/JVM-Tuning
The Adobe website has detailed posts on the exact science of tuning the JVM for your specific server and application(s). Tuning your application, server, JVM, database and network are all part of building a high performance high availability setup. Each is unique and it's really something that should be done no matter which web application layer you choose.
