You have a program that runs on 1/O and processor. On your current system, it has an execution time of 160 seconds. You need to decide which part of your system to invest to improve the overall execution time. You can put a new processor that is 10X faster or a new I/O system that is 100X faster. However, you do not know the fraction of the time the program spends on the processor or the I/O. But you have a 0.1X I/O system from your old setup and you put the old I/O in the current system. You see that the execution time of your program is 448 seconds now. Using these observations answer the following. Find the fraction of the time the program spends on the processor of your current system? Answer: % of the time
