Two more browser developer tools that are useful when auditing performance are Paint Flashing and the Timeline. Paint Flashing displays the regions of the page that are being repainted by the browser. Since repainting can cause performance issues, this helps you identify where the browser’s resources are being used. The timeline allows you capture and analyze a webpage’s loading, scripting, rendering and painting over a period of time.
