I'm not sure why anyone would be downvoting your data point. I am pretty bothered at how much emphasis folks throw behind the TechEmpower benchmarks. If you really dig into the implementations for the top languages, it's easy to see how far from the real world, those apps are. In the case of C#/ASP.NET, as soon as you add EntityFramework (or Dapper, if that's your thing) and some real-world querying of a database. You're looking at a pretty big slow-down. I'm certain things can be done to speed it up though.
