Anka: Designing a Minimal HTTP Server for Native AOT, Its Architecture, and Intentional Constraints
Anka is a minimal HTTP server designed for Native AOT in .NET 8+, focusing on fast startup, low memory usage, and deterministic performance for scenarios like serverless and edge computing. It strips away traditional web framework features like middleware, routing, and TLS to achieve a time-to-ready of 2.3 ms and startup allocations of just 124.5 KB. The architecture emphasizes direct socket handling, connection-level resource pooling, and allocation-conscious async I/O to optimize cold-start behavior.
- ▪Anka reaches a time-to-ready of approximately 2.3 ms.
- ▪Startup allocations are around 124.5 KB with a steady-state RSS of roughly 15 MB.
- ▪It uses parallel accept loops, connection-scoped resources, and SocketAsyncEventArgs for allocation efficiency.

How quickly your service responds to the first request, how little memory it consumes at startup, and how predictably it behaves are now just as important as raw throughput.
