Awesome

This plugin is awesome and behaves smartly.
It takes some time to make sure it’s working with your website – especially on JS files
but after that it rolls. So it’s a very iterative process

Make sure to check the autoptimize cache directory, otherwise you can end up with thousands of files (some JS tweaking required)

It really speeds up your website and compress more files than BWP Minify

Finally futtta, the plugin author provides amazing and comprehensive support!
