I've starting to develop a small web app (by now only for fun, and for learning MVC) using Ruby on Rails and ASP.net MVC3, for learning some background on both systems.
One of the things that I've noticed is that ASP.net is dramatically slower than Ruby (using the default development platforms, Ruby on Mac and MVC3 on Windows/VS2010). I also tried to upload my solution to Azure and test it, but It keeps been slow.
Have you noticed this difference, and how can I improve the performance of my app?
