Performance regression on ASP.NET

[sebastienros]

Could only isolate on this commit range since there were no successful builds for 3 days. Seems to impact all scenarios indifferently.

It doesn't impact NativeAOT (JIT?), and is visible on Windows and Linux.

Could be related to #97399 (comment) . The date doesn't match but there weren't any builds since 1/17 until 1/19 so this could be the same reason.
