Faster CPython at PyCon, part one
Summary: The Faster CPython team, created by Guido van Rossum at Microsoft to improve CPython's performance, presented their work at PyCon 2023. Brandt Bucher explained the meaning of "adaptive" and "specializing" in Python, using an example of a Point class and its shifted() method to demonstrate how the team sped up the interpreter. Bucher used the dis module to disassemble the method and showed how the team optimized the bytecode through "quickening" and "superinstructions". The improvements have already been released as part of Python 3.11, and Mark Shannon will present on the past, present, and future of Python performance enhancements in part two of the presentation.
