Ok, thanks for reporting. This commit was also in 23.03 and 20.11.8 so 
not sure if they were tested on this platform?

This commit fixes a functional issue, so I don't think it should be 
removed unless it is critical issue.

There's no update on other performance report. Release is already 1 week 
overdue, is there critical issues that we should hold release for?

thanks,
Kevin.
