You can call sysconf(_SC_PAGESIZE) to get page size. Problem with transparent huge pages is that you get regular page size (4k) from sysconf(), but then OS sometimes use 2M instead. Just switching to larger regular page size (e.g. 64k) on platforms that support it would not have problems associated with THP.

  We had issue where memory consumption was several times higher with THP enabled. When you hit OOM, such performance problem became correctness problem.
