FANTASTIC

Used it to supplement ‘speed of light’ plugin as that won’t cover caching headers and the other items wpo-tweaks deals with. Tested on pingdom and GTMatrix and scored 100%. Page load 1,8 sec from 3.4 sec beforehand. No recommendations. I also use WPENGINE as my server with EVERCACHE object cacheing, but these 2 plugins filled the gaps they leave out. Highly recommended.
