(Adarsh Divakaran) Python 3.13 was the first Python version released with a free-threaded mode. Although the default interpreter still utilizes the GIL, it provides provisions that enable us to run a free-threaded version of the interpreter with the GIL disabled.
Through this talk, we’ll set up and run the free-threaded interpreter, benchmarking it against the GIL-enabled version for various tasks. We'll assess the impact on single-threaded vs multithreaded code and test the performance across CPU-bound and I/O-bound tasks, aiming to identify scenarios where free-threaded Python excels.
