"Delivering the Goods"


Paul Irish discusses optimization in this keynote talk, describing the "critical path" and how requests impact page load times. Chrome developer tools are used to explain page load sequences and timing. Recommendations include: eliminate render-blocking JS; minimize render-blocking CSS; serve content in the original HTML response and use gzip compression. Google Page Speed Test is a tool to automatically recommend such optimizations.
