If I'm not mistaken, Miguel himself said that Mono was meant for portability (can run on Linux) and not performance. Would be a far better test to use .NET Core as you could still run this test on Linux or any other place where Core runs.

The one exception to what I initially wrote is if Mono was used to compile to native binary (which is what Xamarin apps for iOS do: compile to ARM binary). You'll get very different results if you go that route but that's going to require different compiler options.
