Efficiency of C# on Linux

This week I attended Mads Torgersen’s talk Why you should take another look at C#. Afterward, I asked him about the efficiency of C# on Linux. When I last looked into it, it wasn’t good. A few years ago I asked someone on my team to try running some C# software on Linux using Mono. The code worked correctly, but it ran several times slower than on Windows.

Mads said that now with .NET Core, C# code runs about as fast on Linux as Windows. Maybe a few percent slower on Linux. Scott Hanselman joined the conversation and explained that with .NET Core, the same code runs on every platform. The Mono project duplicated the much of the functionality of the .NET framework, but it was an entirely independent implementation and not as efficient.
