Hi Zia,

do you have HSW performance numbers for this change? An internal bot is logging a >10% regression for MultiSource/Benchmarks/Ptrdist/ks/ks https://smooshbase.apple.com/perf/db_default/v4/nts/graph?highlight_run=114068&plot.746=313.746.3 (O3 flto) pinned to this change. If you can reproduce it perhaps there is a tuning opportunity.

Thanks!
Gerolf
