Overview

Transparent Huge Page (THP) is a mechanism provided by the Linux kernel to optimize memory management.

It automatically merges the default 4 KB small pages into a larger page (usually 2 MB) when conditions are met, to reduce the number of page table entries and improve the Translation Lookaside Buffer (TLB) hit rate. This will reduce memory access overheads and improve the system performance.
