Description
Hi HN,We’ve all accepted the "Python tax"—you trade execution speed for developer happiness. But what if that trade-off was a thing of the past?I just came across BustAPI, and it’s basically a "cheat code" for Python web services. It’s not just another wrapper; it’s a hybrid engine that embeds a Rust (Actix-Web) core directly into the Python runtime.Is this the end of the "slow Python" era? The benchmarks are pretty shocking. I’d love to see someone stress-test this against a production-grade Go or Node.js setup.Repo: https://github.com/GrandpaEJ/BustAPI Benchmarks: https://github.com/GrandpaEJ/BustAPI/tree/main/benchmarks

Could you build this?
No Developing a custom web framework with a Rust core that significantly outperforms established Python servers requires deep systems engineering, low-level HTTP parsing, and PyO3/GIL memory management.
What it would actually take: A production implementation requires an asynchronous Rust core built on Tokio and Hyper exposed to Python through PyO3 or C-extension bindings, handling request parsing and socket pooling natively. The primary bottleneck is achieving safe, zero-copy data transfer and efficient GIL synchronization while maintaining complete ASGI/WSGI specification compatibility.
