    My understanding is that it’s only slightly slower: the OS maintains a pool of zeroed pages anyway, so it’s not like your program has to iterate over all the addresses and write to them.

    But it’s been a long time since I’ve done any C/C++ so I could be wrong.

      TIL, I didn’t know that.
