A computer uses virtual memory, and a new solid-state drive (SSD) as space for paging. Refer to the examples of Time Cost of Page Faults presented in the lectures. In the example presented in class, the hard disk drive (HDD) required 25 ms to read in a page, and a rate of 1 page fault (pf) per 1000 references introduced a 250 slowdown. If the SSD offers a time of only 80 s, what is the slowdown in performance caused by 1 pf per 1000 references (you are not concerned with dirty vs. clean pages). What is the maximum rate of page faults you can accept if you want no more than a 5% slowdown in execution using virtual memory?
