It would seem silly to provision an Tony> ia64 box with less than 16G of memory today. Maybe we should ask for some benchmarks before making this change? IMHO 64KB seems a lot, but maybe it isn't when it comes down to it. I guess it depends a lot on the actual application users are trying to run. I think there are still broken user apps out there that hard code the page size, but then thats not really our problem since we've had getpagesize() in glibc for eons. Cheers, Jes
