What is performance?

Performance, in a technological context, broadly refers to the efficiency with which a system or component achieves its intended purpose. It encompasses various aspects, including speed, throughput, resource utilization (CPU, memory, bandwidth), latency, and scalability. Performance optimization is the process of improving these aspects to enable systems to handle larger workloads, respond faster, and operate more efficiently. Common use cases include web server optimization, database tuning, network optimization, code profiling and optimization, and overall system design improvements.
