64K Kernel Page Size Performance Benefits For Refreshed

This round includes NVIDIA's GH200, along with the AMD & Intel CPUs

Linux 6.8 kernel performance with a 64K page size improved on average by about 15%

@feld My understanding is that to get a larger page size than 64K in Linux, one would have to enable huge pages

Huge pages can use larger memory blocks (e.g., 2MB or 1GB)
