A computer uses virtual memory, using a new solid state drive (SSD) as space for paging Without a page fault, access time is 100ns In the case presented there, the hard disk drive (HDD) required 25ms to read in a page, and a rate of 1 page fault (pf) per 1000 references introduced a 250slowdown If the SSD offers a time of only 80s, what is the slowdown in performance caused by 1 page fault per 1000 references (you are not concerned with dirty vs clean pages assume pages are always clean) 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

A computer uses virtual memory, using a new solid state drive (SSD) as space for paging. Without a page fault, access time is 100ns. In the case presented there, the hard disk drive (HDD) required 25ms to read in a page, and a rate of 1 page fault (pf) per 1000 references introduced a 250slowdown.

If the SSD offers a time of only 80s, what is the slowdown in performance caused by 1 page fault per 1000 references? (you are not concerned with dirty vs. clean pages: assume pages are always clean).
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?
