Hi In the last year there was a lot of improvements done inside Apache MyFaces JSF Implementation (aka MyFaces Core), thanks to the suggestions provided by the community.
To show how good was the improvements done, an in-deep comparison was done between JSF 2 and Wicket. The code, detailed documentation, experimental data and all related information is available here: http://lu4242.blogspot.com/2012/05/understandingjsf-2-and-wicket.html Source code, experimental data and other goodies: https://github.com/lu4242/performance-comparison-java-web-frameworks Detailed document: http://www.scribd.com/doc/94007042/Performance-Comparison-Leonardo-Uribe-FINAL-Detailed This results were part of the CONFESS 2012, celebrated some weeks ago. http://www.con-fess.com In the session called "MyFaces -50% RAM".
