(Linux® systems only: x86, POWER®, and IBM Z®)
If Transparent Huge Pages (THP) is set to madvise on your system, this option, when enabled, promotes all memory allocated to huge pages. On systems without THP, or if THP is set to always or never on your system, this option is ignored. When transparent huge pages are used, your application footprint might increase.
