This is an automated cherry-pick of #56981
What problem does this PR solve?
Issue Number: close #56980
Problem Summary:
What changed and how does it work?
The current sync load monitoring primarily focuses on P95 latency, which is insufficient for capturing extreme timeout issues. While P95 latency may not indicate a timeout, P9999 latency could be significantly high, leading to potential misjudgments and overlooked performance issues.
