Implement more of the techniques and use tools as suggested on: https://speakerdeck.com/addyosmani/css-performance-tooling.

Thanks to @nadavkav for this.

most of the performance will not improve until core chooses a different approach with regards to loading js/css and the php renderer model.

one of the approaches could be to load contextual css (only load forum css when visiting forum) etc. but we can't do this from Essential

True. Just thinking that analysis of the presentation could help in applying more methods.=
