How we are making Python 3.11 faster - presented by Mark Shannon

EuroPython 2022 - How we are making Python 3.11 faster - presented by Mark Shannon

[The Auditorium on 2022-07-14]


The "Faster CPython" project aims to speed up Python, specifically CPython, by a large factor over the next few releases.
The first release to see the benefits of this work is Python 3.11.

Python 3.11 includes the following major changes:

* Adaptive specializing interpreter (PEP 659)
* Consecutively allocated execution frames
* Zero cost try-except
* More regular object layout
* Lazily created object dictionaries.

I will describe each of these, describing how each helps speed up Python, and how they interact with each other.

I will end the talk with some possible directions for Python 3.12.
