To analyze and implement performance improvements in a Unix$-$based system to optimize resource utilization, enhance responsiveness, and ensure efficient handling of workloads. The organization relies on a Unix$-$based operating system for its critical infrastructure. Users have reported occasional slowdowns and performance issues. The goal is to identify and address the factors contributing to the performance degradation.Initial Assessment: Conduct a thorough analysis of system performance using Unix monitoring tools $($e$.$g$.,$ top, vmstat, iostat$).$Identify resource bottlenecks such as CPU usage, memory utilization, and disk I$/$O$.$Identification of Performance Issues: Pinpoint specific areas causing performance degradation. Examine system logs and error messages to identify potential issues.Optimization Strategies: Implement strategies to address the identified performance bottlenecks.Consider optimizing kernel parameters, adjusting process priorities, and optimizing disk I$/$O$.$What specific metrics and benchmarks would you use to quantify the performance improvements achieved through the optimization strategies?
