A computer uses virtual memory, using a new solid state drive (SSD) as space for paging. In the case presented there, the hard disk drive (HDD) required 25 ms to read in a page, and a rate of 1 pf per 1000 references introduced a 250 slow down. (a) If the SSD offers a time of only 70 s, what is the slow down in performance caused by 1 pf per 1000 references? (you are not concerned with dirty vs. clean pages: assume pages are always clean). (b) What is the maximum rate of page faults you can accept if you want no more than a 10% slowdown in execution using virtual memory?
