IsRegressionStdDev: Marked as regression because -25.23297117706907 (T) = (0 -4690.664897499562) / Math.Sqrt((1178.1971485347988 / (23)) + (2849.457621462587 / (4))) is less than -2.0595385527466985 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (23) + (4) - 2, .025) and -0.17460470423885682 = (3993.3986987895732 - 4690.664897499562) / 3993.3986987895732 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

Could the regressions be caused by dotnet/runtime@4322fc9 @EgorBo ?

I'm on a vacation this and next week so can't take a look, sorry 😞
My guess that something is not inlined/devirtualized in Mono for static virtual generics (similar like it was for UTF8 parsing a while back). We plan to eventually rely on ISimdVector in BCL in other places as well to remove code duplication for Vector256 and Vector512 where they basically just duplicate Vector128 path, via this ISimdVector abstraction so it's expected to be zero-cost. Ideally, it allows us to shrink most vectorizations to be 1/3 of their current sizes in C# LOC.

So if it's not urgent I can take a look what Mono/LLVM emits for these and tell exactly what's going on/workaround it once I am back (it's .net9.0 only)

Sorry, I didn't know you are OOF.

It is not urgent, thank you for taking a look after you come back. I will keep an eye on the numbers if we see them back down, I will notify you that it was a false positive. Enjoy the vacation.

Looks like bimodal measurements.
