It's worth adding above the fold (ATF) rendering as a technique. It's aim is to deliver pages on mobile within 1 second and requires a fundamental rethink of the way we architect CSS and our reliance on frameworks like Bootstrap.

Measurement and comparison is the first step in establishing a baseline and then rolling out these techniques and understanding the improvement. http://speedcurve.com/ http://speedcurve.com/ I also discovered CDNConnect recently which looks like a great service to help optimize and generate images at a bunch of different sizes and formats like WebP easily. http://www.cdnconnect.com/ http://www.cdnconnect.com/
