range is dotnet/runtime@df2d213...8fd46b2

@lambdageek possibly dotnet/runtime#106660
@kg could that be jiterpreter part of above PR?

I wonder if always using atomic instructions is penalizing ST perf

None of this is concurrency code and it's AOT, so I don't see how jiterpreter atomics could be responsible.

Oh you're right. I missed this was AOT.

If these benchmarks don't have any interlocked ops, the regression seems unlikely to be due to my PR.
