Traditional web performance analysis often focuses on loading metrics -- time to first render, interactivity, onload, etc. This is important as far as it goes but increasingly limited as web "pages" become "apps" in their own right. While loading metrics remain important, it's becoming crucial to understand what's happening after the page is rendered.
To this end, we'll focus on using Chrome's performance timeline to understand everything that a page does, from the initial page load to ajax requests and client-side rendering. We'll also discuss the tools and techniques at our disposal to eliminate performance bottlenecks, or at least sweep them under the rug when they're unavoidable.
