Your customers are complaining that the system is slow. After doing some research, you learn that you can upgrade your disks for &#036;8,000 to make them 2.5 times as fast as they are currently. You have also learned that you can upgrade your CPU to make it 1.4 times as fast for &#036;5,000. <br /><br />a. Which would you choose to yield the best performance improvement for the least amount of money? <br />b. Which option would you choose if you don&#39;t care about the money, but want a faster system? <br />c. What is the break-even point for the upgrades? That is, what price would be charged for both upgrades to make their cost and performance improvement equal? <br />d. How would you answer if the system activity consists of 55% processor time and 45% disk activity? <br /><br />One of the final exam question in University of Cambridge. Anybody able to answer it? cktio Technical Support Sat, 20 Feb 2010 19:12:38 +0800 http://forum.lowyat.net/topic/1301769 hi, i am doing part-time for PCB design.
