@radekdoulik @radical this looks like something changed in the platform not the code?

[radical]

this looks like something changed in the platform not the code?

Nothing jumps out based on the build at least. Any thoughts on where I should look?

dotnet/performance#3446 was the only difference in dotnet/performance.

[radekdoulik]

this is similar and same range as #23886
