Configure W3 Total Cache for WordPress with Rackspace CDN
Note: Origin pull CDNs work better for sites that experience consistently moderate to high levels of traffic. If your site frequently experiences surges in traffic that might require servers to scale up or down, see Configure W3 Total Cache for WordPress with Rackspace Cloud Files.
