"Mitigating Advertising Impact on Page Performance"
summary
A custom JavaScript loader sits at the bottom of pages and reads a top‑of‑page pageSetup object that declares dependencies, de‑duplicates files, loads core libraries including YUI, and executes JavaScript chunks in priority spaced at 25ms intervals. Iframe ads are late‑loaded by setting src when needed, JavaScript ad calls run after the loader so rendering stays independent of DOM events, impressions change little while full‑page load with ads drops to about 3–3.5s and requests go from 27 to 40.
