Question: Assuming that a web server with the architecture spends20%on processing,30%on disk access, and50%on network transfer, you have a base system consisting of a500MHzprocessor and a disk with20Mbytes/secdata transfer rate. This system costs$5 Kand can support 10,000 average web page accesses/sec. Considering the following three options to enhance system performance: a. Option-1: replacing the existing disk with a disk supporting40Mbytes/secdata transfer rate with an additional(compared to the base) cost of$1,000b. Option-2: replacing the processor with a800MHzprocessor with an additional (compared to the base) cost of$800c. Option-3: using the two enhancements indicated in Option-1 & Option-2 together with an additional (compared to the base) cost of$1,500(1) Determine what will be the new performance (in terms of average web page accesses per second) with each of the enhancement options (2) By doing a cost-performance analysis, determine which option will be costeffective to go for and why?
