Django-Purls

Django-Purls is the simplest way to enable parallelized download of static content on your site. Adding parallelize downloads to your pages may increase response times by 30%.

See http://yuiblog.com/blog/2007/04/11/performance-research-part-4/ for a deeper analysis.

Django-Purls maps static content URLs to one of the configured servers in the PURL_SERVERS settings. Django-Purls uses a consistent hashing algorithm allowing you to add or remove servers without completely re-shuffling all URL mappings and still utilize browser cache.

Supports Python 2.5 or later

Installation

$ easy_install django-purls

Usage

1. Wrap your static content (ex. images) in the purl template tag.

{% load purl_tags %}

{% for image in image_list %}
    <img src="{% purl image.thumbnail_url %}" />
{% endfor %}

2. Install Djagno app and tell Django-Purls about your asset servers

INSTALLED_APPS = (
    ...
    'purls',
)

PURL_SERVERS = {
    # rewrite all URLs using the purl template tag to one of the following
    # servers
    'default': ('assets0.example.com', 'assets1.example.com',
            'assets2.example.com'),
}
