1. PragDave: Is Ruby Better Than ...?:

   ... I’d rather write in a language that let’s me focus on the application, and which lets me express myself clearly and effectively. And, if I can do those two things, I believe that sometimes I’ll be able to write code which is cleverer than something I’d write in a lower-level language. A better algorithm will easily gain back any marginal performance hit I take for using a slower language.
   
   Justin Ghetland experienced this recently on a Rails project. Having coded the same application twice, once in Java and once using Ruby on Rails, he was surprised to discover that the Rails application outperformed the Java one. Why? Justin believes it’s because Rails does smarter caching. The Rails framework contains some very high-level abstractions, and that allows the folks writing the framework to be smart about what they do. They accepted the linear hit of writing in a language that executes more slowly because they got a non-linear increase in speed from being able to write better code.

   Similar point covered earlier.
