I see, i was vaguely aware of them but not to the extent described here. Sadly it seems you need to configure the OS for them - might work for something like a server under your control, but it isn't something you can rely on in general use. I tried to use posix_memalign + madvice MADV_HUGEPAGE to allocate the memory for use in the test program (if i understood the documentation correctly, the "transparent huge page support" that madvice relies on doesn't need any system setup) but didn't see any difference from just using malloc (perhaps the advice was ignored). Either way, both were much slower than just statically allocating the data like in the test program.
