> A new type of interpreter based on tail calls has been added to CPython. For certain newer compilers, this interpreter provides significantly better performance. Preliminary numbers on our machines suggest anywhere from -3% to 30% faster Python code, and a geometric mean of 9-15% faster on pyperformance depending on platform and architecture.
Nice. That would be a speed-bump close to the one we saw on 3.11, even if the JIT is still not production-ready by 3.14 release date.
