Just for the record, my comment didn't intend to imply that JVM frameworks are strictly better in all cases, and I don't believe that at all. In fact, I'd argue that for the majority of applications, choosing any modern framework purely for benchmark performance is very foolish since all of them perform more than adequately. Rails, for example, despite always having been "slow," performs far more than adequately for the vast majority of web applications, scaling patterns are well established, and it's obviously hugely productive for many, many developers and companies.
