I came across these benchmarks: https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/csharp.html

I'm quite blown away how much faster .NET (C#) is than these other languages.  I use C# because it is easy to use, but it turns out to actually be one of the fastest languages too.

It's even faster than C++ in some benchmarks.  

Impressive.
