The main goal here is to measure how Python 3.11 internal speedups affect web frameworks performance. Here we compare Django 4.2 performance on Python 3.10.7 vs Python 3.11.0.

All tests were done on Macbook M1. Steps to reproduce are at the end of the page.

TLDR: it's faster on Python 3.11.

Which cases are way faster now:

Which cases are slower now:

Almost all test points are faster based on avg data from 50 runs.

Raw results are available here in the static folder.

Here are steps to reproduce the results on your local machine. No need to clone this repo, just follow the commands. Standard Django util is used: https://github.com/django/djangobench.

Set up both 3.10 and 3.11 virtual envs. Installing benchmark util and Django in both envs.

cd ~/Developer
mkdir benchmarks
cd benchmarks

python3.10 -m venv .venv310
source .venv310/bin/activate

pip install -e git+https://github.com/django/djangobench.git#egg=djangobench
pip install django pytz

deactivate

python3.11 -m venv .venv311
source .venv311/bin/activate

pip install -e git+https://github.com/django/djangobench.git#egg=djangobench
pip install django pytz

git clone https://github.com/django/django.git
cd django
