My thinking is that this unintialized memory is not really read much until the first write so it is not performance critical. That assumption may of course be wrong. Btw, what programs are reading unintialized memory and why?
But on the other hand, if there is a lot of reading of this zeroed memory, wouldn't a single small page fit better in the cache, thus improving preformance?
