Description
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.
