Does nodejs use less resources than Play framework?
Are there any benchmarks other than http://www.subbu.org/blog/2011/03/nodejs-vs-play-for-front-end-apps
that compares how much resources nodejs uses compared to play framework?
A direct comparison in this case is almost impossible. Because that is completely different instruments based on different technologies. For example a non-blocking IO in node.js and blocking in the Play Framework. But it is possible to implement non-blocking IO in the Play Framework. Results may vary. They will always be vary because the tools are always evolving. Compare something like 'Hello world' is useless. These tests do not show real results. Which tool to choose depends only on a particular task. Application performance depends only on the developer skill.
