Add metric for the time spent updating paint following throttling This patch adds a UMA metric for the time spent updating paint following a frame becoming throttled: Blink.RenderThrottling.PaintUpdateTime This metric will provide two datapoints: how expensive the paint update is (value), and how often it occurs (count). This will only measure one aspect of the full benefit of crbug.com/1325886. For example, this will not measure compositor-thread costs following clearing of paint.

ChromiumChromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
