Accurate, phase-by-phase breakdown of the Critical Rendering Path (CRP) - An insight not given by any other performance tool I have seen. Essential tool for performance enthusiasts.

Excellent extension — it integrates seamlessly and actually feels like a native Chrome feature. It's very helpful for analyzing page performance, with clear visibility into key stages of the critical rendering path, such as DOM building, CSSOM building, layout, and paint. A must-have for anyone working on web performance optimization.

Nice replacement for the old 'page load time' which stopped working.

I really like how the Critical Rendering Path is measured and displayed in the timeline. An elegant and useful add-on.
