In modern backend systems, being “fast” alone is no longer enough. 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. Especially in serverless, short-lived container, edge worker, and bursty internal service scenarios, the real problem is often not steady-state throughput, but cold start performance, startup allocations, and operational simplicity. Anka approaches this problem from the opposite direction of the traditional ASP.NET Core model: no middleware pipeline, no built-in routing, no TLS, no HTTP/2. Instead, it provides a Native AOT-friendly, HTTP/1.x-focused, allocation-conscious HTTP server core built on .NET 8+. The goal is straightforward: once the process starts, begin listening on the socket within milliseconds and keep the connection/request lifecycle as deterministic as possible.…
