The future of Python web services looks GIL-free

Python 3.14 introduces significant improvements to the "free-threaded" variant of the interpreter, moving away from the Global Interpreter Lock (GIL). The latest release shows a performance boost, reducing the performance penalty from 35% to 5-10% compared to the GIL-enabled version. Benchmarks comparing ASGI and WSGI applications on Python 3.14 and the free-threaded variant demonstrate better throughput and reduced memory usage with the free-threaded implementation. While the free-threaded version may be slightly slower for CPU-bound tasks, it offers advantages for I/O-bound workloads, potentially making Python web services GIL-free and more efficient.
