👉 Performance engineering is a systematic approach to designing, building, and maintaining high-performance software systems. It involves identifying and addressing bottlenecks, optimizing resource utilization, and ensuring that applications can handle expected workloads efficiently. This process includes analyzing system performance metrics, conducting load testing, and implementing strategies to improve scalability, reliability, and responsiveness. Performance engineers use tools and methodologies to measure and analyze system behavior under various conditions, making informed decisions to enhance the overall user experience while minimizing resource consumption and maximizing system throughput. By proactively addressing performance issues, performance engineering helps ensure that software systems meet their performance goals and deliver value to end-users consistently.
