System.Threading.Tests.Perf_Timer.ScheduleManyThenDisposeMany has regressed on 64 bit Windows #67972
Description
System.Threading.Tests.Perf_Timer.ScheduleManyThenDisposeMany has regressed on 64 bit Windows (both x64 and arm64).
Looking at the diff which contains only 2 commits I am guessing that it was caused by #60248 (cc @PeterSolMS) but I am not sure.
