Most of the benchmarks seem to stabilize in the upper part of spectrum. The diff is usually dotnet/runtime@1972683...353d5ea, probably only suspect being dotnet/runtime#87656. But I fail to see how that PR would affect stuff in these benchmarks.

Other benchmarks suspiciously similar to as #22151 (comment).
