Django-Speedboost
Replaces select Django modules with Cython-compiled versions for great speed.
Rationale
Code always has bottlenecks, and Django is no exception. By selectively compiling the hot spots in Django with Cython, we can make it go faster. Django-Speedboost is a drop-in module that when installed replaces parts of Django with its Cython-based versions.
Requirements
Python: 2.7
Django: 1.8.8
Django-Speedboost’s test suite runs the Django test suite after installation to verify that it doesn’t do anything incompatible.
Installation
Django-Speedboost is currently compiled for Django 1.8.8 only. Install with:
pip install django_speedboostIf you get missing header compilation errors, install your distribution’s python library development headers, for example on Ubuntu:
sudo apt-get install libpython-devHow It Works
Django-Speedboost includes a .pth file that allows it to import itself at the point the Python interpreter loads. It uses this to install an import hook that detects the loading of Django submodules to replace them.
Currently replaced modules:
django.template.context
django.template.context_processors
django.template.base
django.template.defaulttags
Results
Setting Django with WSGI behind Apache 2, ab shows a consistent 13% reduction in load times on an Admin page with loads of inlines and fields:
