lewing · 2023-01-18T00:23:29Z

@radical can you check the versions here to make sure this isn't the version switch

radical · 2023-01-18T00:37:39Z

Both baseline, and compare have the full net8.0 switch changes.

stephentoub · 2023-01-18T00:41:29Z

If RuntimeHelpers.CreateSpan isn't optimized well on mono, I could certainly imagine dotnet/runtime@2897f5e contributing to these regressions.
