HugeTLB Pages

HugeTLB pages are also called static huge pages.

With HugeTLB pages feature, you can reserve pools of huge pages, each of a specified quantity, for each huge page size. The available huge page size options on x86_64 platforms are 2 MB and 1 GB.

Note:

Best Practices:
  • Make requests to the kernel for static huge pages as close to boot time as possible, when the occurrence of memory fragmentation is at a minimum.
  • Huge pages can reduce the amount of memory available to the system. Therefore, when requesting a reserved huge page pool, ensure the pool isn't oversized and that the system’s access to memory isn't impacted.
