Despite the 3 page flip flake threshold, flex has seen a significant increase in CPMH since m130 over this threshold logic. After various attempts to reproduce the issue and discussion over possible memory leak, it was decided that the probable cause is that Flex- by virtue of using legacy page flips and having little-to-no overlap promotion support- flake page flips more often. To determine a good threshold for page flip flakes on Flex, we will up the threshold on Flex for a month and count the number of page flips flakes in a histogram. There will be overcounting: a device that flakes 3 times in a row will also emit a metric for "1 flake" and "2 flakes," but we are more concerned with finding the upper limit of flakes rather than specific counts.

Chromium
Chromium 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.
