Lily’s cоmputer is running slоwly. With yоur expertise in systems, you’ve been аsked to recommend upgrаdes thаt will enhance its performance. (a) [10pts] First, you profiled her computer and found out that fetching a page from memory takes 100ns and fetching it from the swap disk takes 20us, and the page fault rate is 50% on her computer. What is the average page access latency? (Hint: 1us = 1000ns. A 50% page fault rate means that 50% of the page references cause page faults.) (b) [5pts] The first upgrade option is to increase the computer’s memory size. Assuming that doubling the memory size can reduce the page fault rate to 25%, what is the average page access latency after this upgrade? (c) [5pts] The second upgrade option is to install a faster disk for swap. Assuming that this upgrade can reduce the latency for fetching a page from swap to 10us, what is the average page access latency after the upgrade?
