Huge pages can improve performance by increasing translation lookaside
buffer (TLB) utilization and reducing memory-management overhead.
Transparent huge pages (THPs) are supposed to make huge-page usage,
well, transparent, Nico Pache said at the beginning of his session in the
memory-management track of the 2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit. That transparency has
never worked as well as many would like; he has been working on
improvements to make it easier for applications to use huge pages on Linux
systems. A following session, led by David Hildenbrand, was focused on how
THPs could be taken away from processes that are not using them fully.
