@monzu02, after looking into this plugin and trialing and testing this is what I find.
This is a very powerful and helpful plugin. The plugin does work and it can improve your site speed. However you need to do your homework and it is not always going to give you the results you are looking for. If you don’t get the results that you require it does not necessarily mean that the plugin does not work. This could means that some other setting in your site might be conflicting with other settings or it might be that other plugins are conflicting with each other. It also means that you need to carry out many tests until you get the results you are after.
Oh and you also need to be somewhat technical minded as well to fully understand this plugin.
At the end of the day this is a great plugin and I am getting to like it more. The more I use it the more I understand the plugin, the more I love this plugin.
A 1 star rating without understanding the complexity and functionality of this great plugin is not very positive for the developer and is not a credit to this plugin.
My humble opinion.
