PERF

PERF is a tool used by developers and system administrators to analyze the performance of a computer’s hardware and software. It helps identify what parts of a program or system are taking the most time or resources, such as CPU, memory, or input/output operations. By collecting detailed data, PERF allows experts to pinpoint bottlenecks or inefficiencies, enabling them to optimize and improve overall system speed and responsiveness. Think of it as a diagnostic tool that provides insight into how your computer's processes are functioning, helping ensure everything runs smoothly and efficiently.
