[$] Faster CPython at PyCon, part two

In part one of the tale, Brandt Bucherlooked specifically at the CPython optimizations that went intoPython 3.11 as part of the Faster CPython project. More of that workwill be appearing in future Python versions, but on day two of PyCon 2023 in Salt Lake City, Utah,Mark Shannon provided an overall picture of CPython optimizations,including efforts made over the last decade or more, with an eye toward theother areas that have been optimized, such as the memory layout for theinternal C data structures of the interpreter. He also described someadditional optimization techniques that will be used in Python 3.12and beyond.
