Suppose that you currently have a computer system with the following two characteristics: There are only three components that determine the overall performance — CPU, memory, and disk. For any given computation, the system spends 30% of the time for CPU, 40% of the time for memory, and 30% of the time for disk. Now suppose that you want to purchase a new system that improves the performance in the following ways: The memory performance is 4 times faster over your current system, the disk performance is 5 times faster over your current system and everything else is the same. Using Amdahl’s Law, calculate the overall speedup of the new system over your current system

Question

Suppose that you currently have a computer system with the following two characteristics:
There are only three components that determine the overall performance — CPU, memory, and disk.
For any given computation, the system spends 30% of the time for CPU, 40% of the time for memory,
and 30% of the time for disk. Now suppose that you want to purchase a new system that improves the
performance in the following ways:
The memory performance is 4 times faster over your current system, the disk performance is 5 times
faster over your current system and everything else is the same. Using Amdahl’s Law, calculate the
overall speedup of the new system over your current system.
