Replaces select Django modules with Cython-compiled versions for great speed.

Project Description

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_speedboost

If you get missing header compilation errors, install your distribution’s python library development headers, for example on Ubuntu:

sudo apt-get install libpython-dev

How 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:
