 as KPI

 After upgrading WordPress from v5.9.3 to v6.0, we found that the
 performance dropped.

 After experiment on ` git cherry -v 5.9-branch 6.0-branch |cat -n >
 ~/commits_on_6.0_branch.txt`  totally 707 commits, root cause addressed
 due to [https://github.com/WordPress/wordpress-
 develop/commit/bab610091d59f6dd21c7db84ba3e1ca0bab6a211 this commit].
