AsyncIO‑Cython vs GIL Threading 2× Speed Software Engineering
AsyncIO paired with Cython can deliver roughly twice the speed of classic GIL-bound threading for many Python workloads, especially when I need both I/O concurrency and raw compute acceleration. Software Engineering: Mastering the Python GIL Key Takeaways * GIL limits true parallelism in CPython. * Thread pools often waste core cycles.
