Dear All, I think Ruby and JRuby both have their advantages. It depends on the environment which one is easier to integrate and maintain. In a typical Linux-Apache-(Postgres|MySQL)-Ruby environment JRuby with its additional requirement of Java comes with some painful extra cost, which can otherwise be avoided. In an java-enviroment, where part of the stuff should be done with Ruby+Rails it might be the other way round.
My own observation is that JRuby is slightly faster than Ruby 1.8.7, but Ruby 1.9 is way faster than that. But it depends on what Java you use, what you do etc.. I would like to point out that the set of libraries available may be quite different. Many Ruby-libraries use native c-code and are unavailable in JRuby. Another point is that operating-system-functionality is not really available in Java beyond what can be commonly implemented on different platforms supported by Java. So they are not easily accessed in JRuby either. If such stuff is needed, native Ruby is better. I have even used native Ruby to add Windows- and Linux-specific functionalities for accessing OS-features needed and hidden in Java from a Java software. So I would really recommend to carefully consider which one is better.
