I have found this to be an essential plugin for my website. It has managed to reduce page load time from 10-20 seconds to 1-2 seconds.
Its far less confusing then other similar plugins and gives better results.
I spent days with other plugins reading set up guides and trying to configure but just couldnt get them to work right. This plugin had less tick boxes but still seemed to do the same job if not more and i could test out different settings and tweak it until i had optimum performance without really knowing what i was doing, but just by testing each feature until it was perfoming best...
I got it to a point where performance waas great. however a few plugins had stopped displaying.... its to my understanding these can be excluded from optimization with a bit of intstuction from FAQ and a bit of code pasting, but this seemed a bit beyond me, so i searched for a plugin and found plugin organiser. This plugin allows for you to select which order the plugins load and you can specify which plugins load on which pages, this easy to use plugin fixed that problem and is a good little plugin itself for keeping plugins organised. It compliments autoptimize a treat :)
