Show your steps and how to find. Please type reponse.
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 have learned that you can upgrade your disks for $8,000 to make them 2.5 times as fast as they are currently. You have also learned that you canupgrade your CPU to make it 1.5 times as fast as the current CPU for $5,000.
a. Which upgrade option would give a faster system?
b. Which upgrade option would give the best return of investment for each percent of speed improvement?

Explanation / Answer

Answer a) The upgrade option for the cpu by investing $5,000 would give a faster system as the load on the system is divided as 60% on cpu and 40% on disk activity, therefore as the load on the cpu is more in comparison to the disk activity therefore it needs to be upgraded for sure.

Answer b) The upgrade of the cpu would give the best return of investment as the amount of upgrading of cpu is comparatively as that of disk. The requirement for the upgrade in cpu was more as the load was much more on the cpu.
