Python 3.11 Performance Benchmarks Are Looking Fantastic #Python @phoronix

Last month Python 3.11 Beta 1 was released as their first preview of this major update to the Python programming language. Besides new language features and other improvements, Python 3.11 performance is looking fantastic with very nice performance uplift over prior Python 3 releases.

Python 3.11 has been baking support for task groups in asyncio, fine-grained error locations in tracebacks, the self-type to return an instance of their class, TypeVarTuple for variadic generics, and various other features.

Besides changes affecting the Python language itself, Python 3.11 has been landing performance work from the “Faster CPython Project” to speed-up the reference implementation. Python 3.11 is 10~60% faster than Python 3.10 according to the official figures and a 1.22x speed-up with their standard benchmark suite.

Phoronix ran the latest beta through a suite of test programs and the results are impressive. An example:

When taking the geometric mean of all the Python benchmarks I carried out for this article on the AMD Ryzen 9 5950X, Python 3.11 Beta was about 41% faster overall than the current Python 3.10.4 stable release or 45% over the aging Python 3.8 series. All the individual benchmark data can be found via this OpenBenchmarking.org result page.

Read the entire test process from Phoronix.
