Sunil's response demonstrates a practical understanding of identifying and resolving performance issues related to hardware upgrades. He describes addressing slowness by upgrading from a traditional hard drive to an SSD and increasing RAM from 4 GB to 8 GB. However, his explanation lacks clarity and structure compared to the benchmark response, which provides a more detailed and organized account of the process. Sunil could improve by clearly outlining the steps taken and the impact of each upgrade on system performance.
