Suppose that we want to enhance the processor used for Web serving. The new processor is 10 times faster on computation in the Web serving application than the original processor. Assuming that the original processor is busy with computation 45% of the time and is waiting for I/O 55% of the time, what is the overall speedup gained by incorporating the enhancement?
