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

Default:

'' (empty string)

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

WEBPERF_DOMAINS_NUMBER

Default:

2

Number of domains you want to use to split your media content.

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