State of Python 3.13 performance: Free-threading
Python 3.13 is out and it's time to run some benchmarks to see how well it performs with the new free-threaded mode.
The traditional solution has been to use the multiprocessing module, which spawns separate Python processes instead of threads and while this approach works, it comes with significant limitations: At that point, migrating to the free-threaded build should be a no-brainer for a lot of parallel applications and it will be interesting to measure the performance changes. From this measurement, we can see that the new free-threaded build of CPython 3.13 can have a significant impact on the performance of parallel applications, bringing a very relevant alternative to multiprocessing.
