Simple and worked great

There were no settings or anything to adjust or play with – just activated the plug-in and it went to work. Dramatic improvement at Google Site Speed ratings. No issues that I’ve seen at the site. One thing is if you are still developing your site you may want to wait until the end as it minifies the code so it makes it harder to read if you are looking for issues on your site. (I assume you can just deactivate the plugin – but I haven’t done that yet).
