@hydn, our comments should be AutOptimize forum posts, so people considering that plugin will see them. However, I want to confirm that what you wrote above is true. Over the past several days I have installed and throughly tested all the various minification/caching/cdn plugins I could find at a test site that has pages loaded with unusually rich content (multiple large css files, multiple htc files, many images, audio, video, multiple JavaScript files, etc.). Most of the plugins I tried are seriously flawed by coding mistakes, fallacious underlying design logic, poor html header parameter choices, misleading setup information, and/or operating system incompatibilities. In contrast, AutOptimize and WP SuperCache work together flawlessly on both Linux and Windows servers (running Apache, I haven’t tested with other web servers). Both plugins are simple to install and configure, and when used together page loading times half way around the planet are phenomenal.
