### Payloads [Baseline]() [Compare]() ### Histogram #### System.Security.Cryptography.Tests.Perf_CryptoConfig.CreateFromName(name: "SHA512") ```log ``` ### Description of detection logic ```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. 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 1.7474771236476567 > 1.7439033112354578. IsChangePoint: Marked as a change because one of 5/23/2022 1:47:22 PM, 7/13/2022 5:51:45 AM, 7/18/2022 2:17:16 AM falls between 7/8/2022 10:31:34 AM and 7/18/2022 2:17:16 AM. IsRegressionStdDev: Marked as regression because -9.622511526334701 (T) = (0 -1828.0051082277446) / Math.Sqrt((4277.201437825288 / (34)) + (2024.235730676065 / (20))) is less than -2.0066468050606243 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (20) - 2, .025) and -0.08614349420215779 = (1683.0235765215643 - 1828.0051082277446) / 1683.0235765215643 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. ``` ### Docs [Profiling workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/profiling-workflow-dotnet-runtime.md) [Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)
