Doesn't that make it slower because it needs to zero out all the bytes first?

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.
