Amdahl’s LAW Question: Suppose that we want to enhance the execution time used for web serving, two designs have been proposed, show which one is better
Design 1: Use a new processor 15 times faster than the original processor, assuming that the original processor is busy with computation 50% of the time and waiting for the I/O 50% of the time.
Design 2: Use a new Processor 20 time faster. While the processor is 30% of the time busy with the computation and 70% waiting for the IO

Explanation:

As per Amdahl's law :

Here :

Design 1:

FractionEnhanced = 0.5 (50% of computation )

[ Note that I/O wait has nothing to do with speed ]

SpeedupEnhanced = 15 times

========

Design 2:

FractionEnhanced = 0.3 (30% of computation )

SpeedupEnhanced = 20 times

========

So as we can see Design 1 is better with overall speedup of 1.876 times the original processor.
