Django Web Performance
A collection of stuff to improve django web performance.
Domain sharding
Domain sharding is an optimization technique for parallelization of resource loading. If you have a lot of media files on your page you might want them to be downloaded from different domains, as web browsers have limits on how many files they can grab at once. Domain sharding reduces the overall page load time and is widley used on rich media sites, like Facebook, Youtube, etc.
It works as a customized django file storage, overriding standard url method.
Installation & setup
Recommended way to install is pip:
pip install django-webperf
Make sure to change your DEFAULT_FILE_STORAGE in settings.py to use sharding site-wide:
DEFAULT_FILE_STORAGE = 'web_performance.storage.DomainShardingStorage'
Settings
WEBPERF_MEDIA_TEMPLATE

'' (empty string) |

A pattern to generate media_urls with a standard format placeholder. E.g. http://img{0}.example.com/media/
WEBPERF_DOMAINS_NUMBER

Don't use too many domains, becasue it will increase DNS lookup time.
