I'm surprised you didn't include ASP.NET Core's server (Kestrel) in your benchmarks, as it tends to be one of the faster servers (eg. see TechEmpower's benchmarks: techempower.com/benchmarks)
j You don't need Mono any more, Microsoft have a new framework (.NET Core) that's cross platform. You don't need Windows for development either, it works very well with Visual Studio Code on MacOS and Linux too. :)
