Grails more productive than Rails

Catchy title. But the guys from ALTERthought have some - much needed - numbers. Their numbers show Grails to be more productive than Rails, which is in turn more productive than Spring and pure JEE. As I've argued for years, there is no science in computer science. We need to put facts back into computer science. Hard numbers instead of faery tales. Hacknot thinks so too. Thanks for the real numbers. Two thoughts:

  1. This is development effort, not maintenance. Glass shows that 40 to 80 % of effort go into maintenance.
  2. We compared Grails to Seam and think they have much in common. Seam productivity should be nearer to Grails than to the standard JEE stack

Thanks for listening.
