Extract: For those reasons, the standalone prefetcher uses an algorithm
to handle long, complex streams with larger training structures,
and techniques to reuse learnings across 4KB physical page
crossings.

So all those measures on real code, and core improvements following these measures, would they be impacted by the fact Apple has chosen 16 Kbytes/pages at the OS level?
