Performance¶
Level: L2 | Domain: devops
Performance engineering is the practice of measuring, analyzing, and improving the speed, throughput, and resource efficiency of systems. It encompasses profiling, load testing, bottleneck identification, and the scale-vs-optimize decision framework.
Performance work requires data -- profiling before optimizing, measuring after changes, and understanding whether the bottleneck is CPU, memory, I/O, or contention before choosing a mitigation strategy.
