Suppose the daytime processing load consists of 60% cpu activity and 40% disk activity. your customers are complaining
that the system is slow. after doing some research. you learn that you can upgrade your disks for $8,000 to make them 25
times as fast as they are currently. you have also learned that you can upgrade your cpu to make it 14 times as fast for
$5,000.

a) which would you choose to yield the best performance improvement for the least amount of money?

b) which option would you choose if you don‘t care about the money, but want a faster system?

c) what is the break-even point for the upgrades? that is, what price would we need to charge for the cpu (or the disk—
change only one) so the result was the same cost per 1% increase for both?
