The diff is roughly 44a5abd...848c729. Could #87672 be the reason? cc @kouvel

[kouvel]

It seems unlikely to me that #87672 could cause it, the Lock type is not used by anything in coreclr currently and the remaining changes in the PR were only minor changes that don't appear to be perf-related.

The overall trend seems to be in noisy range.
