" summary

Demos show concrete tools and results: dynaTrace AJAX Edition 2.0 beta captures rendering, JS execution and server pure‑paths and finds a 2.4s class lookup and 2.5s handler blocking first visual impression; Firebug 1.6 adds paint events, panel navigation and net export (HAR) for sharing traces; YSlow is extensible with a simple rule API and cronable monitoring; PageSpeed and its C++ SDK surface exact optimizations, identify deferred loading of javascript and CSS candidates, and a Chromium+service demo returns actionable JSON — all demos run and produced reproducible diagnostics.
