A five-star bake. Worth schmearing, sharing, saving.
Summary
The article analyzes performance issues with Unity's Mono runtime for C# code execution, comparing it to modern .NET. The author found that their game runs 2-3x faster on modern .NET compared to Unity's Mono, with some benchmarks showing up to 15x speed improvements. The article investigates why Unity's Mono implementation is slow by today's standards and advocates for Unity's .NET modernization to become production-ready sooner.

· 4 pulledExecution of C# code in Unity's Mono runtime is slow by today's standards, much slower than you might expect!
Our game runs 2-3x faster on modern .NET compared to Unity's Mono, and in a few small benchmarks I measured speedups of up to 15x.
Unity uses the Mono framework to run C# programs and back in 2006 it was one of the only viable multi-platform implementations.
I will present my findings and why everyone should want Unity's .NET modernization to become production-ready as soon as possible.
