Performance Analysis

Definition

Performance analysis is the systematic evaluation of a system's output relative to its input, focusing on measuring how effectively a system performs its intended function. This involves assessing various metrics such as power output, efficiency, and resource utilization to determine areas for improvement and optimize overall functionality.
