We have a working prototype and a desire to create a production release. The major concern is the resource utilization per user.
I am relatively comfortable with the J2EE scalability and the ability to distribute the load, but are there any known large scale JBP implementations that can be referenced? White papers? Are there any configuration or coding guidelines to have an application with MySpace-like scalability?
Are there any comparisons of resource utilization of JSF vs Struts or even other approaches, such as PHP?
