### Payloads [Baseline]() [Compare]() ### Histogram #### System.Memory.Span<Byte>.IndexOfValue(Size: 512) ```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 205.79136066734551 > 202.25785394043595. IsChangePoint: Marked as a change because one of 1/27/2023 11:36:27 AM, 2/9/2023 12:40:40 PM, 2/15/2023 12:21:17 PM, 2/23/2023 8:54:44 PM, 3/2/2023 2:22:24 PM, 3/22/2023 1:04:34 PM, 3/28/2023 8:13:28 AM falls between 3/19/2023 2:30:51 PM and 3/28/2023 8:13:28 AM.

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)
