" summary

Demonstrations cover concrete tools and outcomes: webpagetest.org hosted runs IE plug‑in tests from selectable locations and speeds, supports first/repeat views, object blocking (useful to remove ads), produces permanent result URLs, waterfalls and a new connection view, plus best‑practice compliance reports. HTTPWatch offers IE/Firefox plugins and a programmatic API that yields load time, bytes, compression savings and round‑trips. YSlow 2.0 exposes 22 rules, customizable rule sets and add_rule JS hooks and integrates Smush.it. VRTA visualizes TCP packets via NetMon; Firebug nets panel exports traces and can break on XHR.
