Next gen optimizations

[pmeenan]

Do you have a link to a test result or a page that you can share? It's unusual for someone to have exhaused all optimizations so there may be some not-obvious ones (Data URI's, async scripts, etc).

Unless you have HUGE amounts of whitespace it won't have a measurable impact. It will use more memory and take a little longer to parse but it should compress away on the wire so you're probably talking microseconds (depending on how much whitespace).

Megabytes of whitespace could certainly be an issue, particularly for mobile.
