:jmaher Lots and lots and perf improvements on Windows from now on -- perf baseline update. I filed this bug only to highlight the PGO regressions according to tp5o. Their OPT counterparts record quite the opposite: perf improvements. I guess I can close this bug as WORKSFORME, as it sounds like a temporary glitch? Also, if I blocked the wrong bug from the patch, please adjust this.

yes, thanks for filing this- this change is just the new hardware and the PGO only regressions are confusing but not really actionable if OPT is an improvement.
