# Introduction #
The .NET runtime supports a wide variety of high performance applications. As such, performance is a key design element for every change. This guidance is designed to share how we collect data and analyze the performance of the runtime.
+CoreFX performance guidance is available [here](https://github.com/dotnet/corefx/wiki/Performance).
