It is a good and interesting observation, but as the benchmarks approach real-world scenarios, the difference is more than a millisecond or two. For instance, if you're running on EC2 hardware (which is common enough) and you're executing ~20 DB queries/request (which is probably, unfortunately, common enough), the difference between Java servlets and Rails is more like 10ms. Then what happens when more than 89 real-world users start to hit your Rails server each second? (Note: I really like Ruby and Rails. Much more so than Java and its offerings.)
