Suppose that for a given job, Belady’s min would result in a 99.99% hit rate, that memory access time is 70 nS, and that disk access time is 12 mS. If NFU results in 20% more page faults than Belady’s min, and second chance results in 30% more page faults than Belady’s min, how much is the average access time degraded for each of these page replacement policies?
