Hello, I'm coming from a Rails background and was very impressed by the features of the Yesod Web Framework. Working on an trading app in Rails I wanted to port some features of this app to a Yesod app just to learn the framework and because we have some performance issues with Rails. The first thing I noticed was that the Yesod app was significantly slower than the Rails app at trivial tasks. I am very astonished about that. I thought Rails should be slower because of its interpreted nature. I made some benchmarking and measured that a simple Rails app is fourteen times faster than a Yesod app that did the same thing (loading some records from the database and displaying them). Did I made a mistake or is my understanding, that the compiled app should be faster, just wrong? I documented the results on github: https://github.com/SKoschnicke/performance-test Greetings Sven Koschnicke
