C# recently came out with Native AOT (ahead of time) compilation that compiles your app to a binary that can run without the .NET runtime (!!), and has fast startup and lower memory overhead. There are a few drawbacks: many reflection and run-time code generation and loading features are unavailable, and LINQ expressions must be interpreted which makes them slow. But it's easy to work around those limitations for a greenfield infra project, and C# has great performance characteristics.
