Another pitfall cited in Section 1.10 is expecting to improve the overall performance of a computer by improving only one aspect of the computer. Consider a computer running a program that requires 250 s, with 70 s spent executing FP instructions, 85 s executed L/S instructions, and 40 s spent executing branch instructions.

1. By how much is the total time reduced if the time for FP operations is reduced by 20%?

2. By how much is the time for INT operations reduced if the total time is reduced by 20%?

3. Can the total time can be reduced by 20% by reducing only the time for branch instructions?
