This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



While browsers can handle up to 60 http requests simultaneously, only 2-4 simultaneous requests can be handled from the same hostname. This can potentially slow down page loads on your site.

The solution Recommended by Google is parallizing resources across 2-5 hostnames on sites serving 10 or more static resources.

Parallelize allows automatically parallelizing WordPress attachement files (images or any files uploaded with the wordpress media features) across multiple hostnames, speeding page load. To assist caching, resources will always load from the same hostname.

This plugin is distributed as-is, no warranty whatsoever.
