I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

kunalspathak · 2022-05-24T16:27:18Z

@DrewScoggins - Seems we didn't have run for few days. Can we do catchup runs to narrow down the commit that caused the regression?

jeffschwMSFT · 2022-05-26T15:00:57Z

Assigning to Extensions label until we can get an updated commit range.

Looking at the list of commits 6e4eba8...15dda0e I am not seeing any commit for logging nor globalization which can cause any regression.

@AndyAyersMS do you think 41491a3 can cause such regression?

Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 152.52610072861836 > 127.9248302742737.
IsChangePoint: Marked as a change because one of 4/16/2022 5:36:25 PM, 5/18/2022 10:04:15 AM, 5/24/2022 7:58:36 AM falls between 5/15/2022 6:57:22 PM and 5/24/2022 7:58:36 AM.
IsRegressionStdDev: Marked as regression because -118.11814837328622 (T) = (0 -153.1034076811276) / Math.Sqrt((1.0526317590992857 / (33)) + (0.836670892446692 / (24))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (33) + (24) - 2, .025) and -0.24896454796812012 = (122.5842702502678 - 153.1034076811276) / 122.5842702502678 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.

@AndyAyersMS do you think 41491a3 can cause such regression?

No, it was a bug fix for a very rare case.

Seems like whatever the cause of these regressions, most now are faster now -- perhaps we can just close this.

tarekgh · 2022-08-03T15:54:21Z

Per @AndyAyersMS reply, I am closing this issue for now as the regression is not there anymore. Thanks @AndyAyersMS!
