Overview
Transparent Huge Pages (THP) is a feature provided by the Linux kernel to optimize memory management.
It automatically merges the default size pages (4 KB) 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 reduces memory access overheads and improves system performance.
