Disk is actually slower than that. The seek time (for any size transfer) is generally comparable to the time-slice in your environment (at least on those machines which presently have big memories - Cray, Cyber 205, etc). Since your program loses its time-slice on every page fault anyway, the page size might as well be large. But, then again, I'm not really in favor of virtual memory on large machines anyway. J.
