summary
Describes measurable claims and concrete fixes: the performance Golden Rule shows only 10–20% of page load time comes from server-side HTML and 80–90% from browser work, pages average ~40–50 HTTP requests, and HTTP/1.1 limits two connections per hostname so many resources stall. Recommends spriting (combine ~20 images into one), use a CDN (Akamai, Limelight), and tools like Firebug + YSlow (a Firebug add-on released open source that reports missing Expires headers, excessive requests, and actionable rules). Presents 14 prioritized rules and new JavaScript-focused optimizations for faster client-side performance.
