Question: Assuming that a web server with the architecture spends 20% on processing, 30% on disk access, and 50% on network transfer, you have a base

Assuming that a web server with the architecture spends 20% on processing, 30% on disk access, and 50% on network transfer, you have a base system consisting of a 500MHz processor and a disk with 20Mbytes/sec data transfer rate. This system costs $5K and 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 supporting 40Mbytes/sec data transfer rate with an additional(compared to the base) cost of $1,000 b. Option-2: replacing the processor with a 800MHz processor with an additional (compared to the base) cost of $800 c. 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
