Talks - Mark Shannon: How we are making CPython faster. Past, present and future.

Many of you will will have heard that Python 3.11 is considerably faster than 3.10. How did we do that? How are we going to make 3.12 and following releases even faster? In this talk, I will present a high level overview of the approach we are taking to speeding up CPython. Starting with a simple overview of some basic principles, I will show how we can apply those to streamline and speedup CPython. I will try to avoid computer science and software engineering terminology, in favor of diagrams, a few simple examples, and some high-school math. Finally, I make some estimates about how much faster the next few releases of CPython will be, and how much faster Python could go.
