Start by reviewing the three reported benchmark scenarios and the PowerBI dashboard, then compare the commit ranges linked for Microsoft.AspNetCore.Antiforgery.dll, Microsoft.AspNetCore.App, and Microsoft.NETCore.App. Re-run the antiforgery-noop, json, and mvc benchmarks to confirm the regression; done means identifying and addressing the change responsible for the lower RPS.
