1. Python 3.15’s interpreter for Windows x86-64 should hopefully be 15% faster Total comment counts : 22 Summary The author revisits tail-calling CPython performance across two platforms. On macOS AArch64 (XCode Clang), tail-calling interpreters are about 5% faster than computed-goto counterparts on pyperformance. On Windows x86-64 (experimental MSVC), tail-calling yields roughly 15–16% speedups, with a wide range (some benchmarks up to ~60–78% faster, a few slower). Results are experimental for MSVC, but largely positive overall; larger libraries like xDSL show ~14% gains....
