Description

[[:owlish] 🦉 PST]

It might be instructive to investigate how the priority of the processes is being Managed in Chromium and what are their conditions for tab reloads/unloads.

• The codebase can be found here https://source.chromium.org
• A point to start might be Java_ChildProcessLauncherHelperImpl_setPriority function and its Java counterpart
• Function that updates the process on C++ side

This investigation has been done and reported in several subtitles of the following document:
https://docs.google.com/document/d/1s9AqQ9Ixi-NzoitztuhEeP67-hvcUq7DHDZ6YbiWlS4/edit#

As seen from the document Fenix and Chrome comparison is also done. The document also mentions APIs that exist in Chrome but not in Fenix (such as ZygotePreloader) that cause a difference in the memory consumption of the content processes.

I think we can close this ticket.
