I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here.
So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ?
Or do you have your own performance tests for grails (compared to others if possible) ?
