Here is a list of the benchmarks that I have found. It is ordered by relevance.
- World Wide Wait: It is a one-hour long conference but the benchmark is quite accurate. GWT, Spring, JSF, Wicket and MyFaces are compared.
- Rails, Wicket, Grails, Play, Tapestry, Lift, JSP, Context: A group of products has to be rendered with its categories. Response time with 1 user and with concurrent users is measured. Database is not used, memory is used instead.
- The Great Web Framework Shootout : According to its author “It would be foolish to consider these results as scientific in any way” . Nevertheless, I found this imprecise benchmark interesting because it compares PHP, Python and Ruby frameworks.
