On 2.4, there are some interesting filesystem issues with a 64KB page size. Besides that, 64KB obviously leads to much higher internal fragmentation, so I wouldn't recommend it for systems with "small" amounts of memory (less than a couple of gigs). On the other hand, the performance measurements I have done with 64KB page size suggested that the page size could become the sweet-spot much sooner than I had expected. It wouldn't surprise me if 2-3 years from now, we started seeing normal distributions ship with 64KB page size by default (and of course, for special environments/applications, 64KB page size makes tons of sense today already). --david
