Intel’s open-source software engineers are known for many great performance optimizations to the Linux kernel. Over the years Intel has contributed countless performance optimizations to the kernel and related Linux components that have made significant improvements not only for Intel hardware but x86_64 as a whole and at times CPU architecture independent improvements. One of their newest performance optimizing patch series is around Per-CPU Pageset (PCP) high auto-tuning.
The new patch series is focused on tuning the per-CPU pageset high on each CPU automatically to optimize the page allocation performance.
