First of all, kudos for the following blog/post: JSFCentral - Understanding JSF 2.0 Performance - Part 3[1]
I started reading this, and not done yet. >> Instead, it's more interesting to check the ability of a web framework to deal with effects like concurrency and get an idea of the overhead involved in using a web framework against the fastest possible solution in Java. So far, I'm seeing, possibly, latest releases of open source software used in the test...except for the JDK. Does 'fastest possible solution in Java' = JDK6.0.30? JDK7 has been available for quite some time and I know I'm using JDK7 (latest version, always), and JDK8 is out there and around the corner. Is there any reason why Java = JDK6.0.30 in the tests?
