Performance Analysis
Performance analysis is the systematic process of measuring, evaluating, and optimizing the efficiency and responsiveness of software applications, systems, or components. It involves identifying bottlenecks, resource usage patterns, and latency issues to ensure applications meet performance requirements and user expectations. This practice is critical for maintaining scalability, reliability, and user satisfaction in production environments.
Developers should learn performance analysis to diagnose and resolve slow or inefficient code, especially in high-traffic web applications, real-time systems, or resource-constrained environments like mobile devices. It is essential during development cycles to prevent performance regressions, in production to troubleshoot issues under load, and for optimizing algorithms, database queries, or network calls to reduce costs and improve user experience.
