CPU Usage
CPU usage is a performance metric that measures the percentage of a computer's central processing unit (CPU) capacity being utilized over a period of time. It indicates how much of the CPU's processing power is actively executing tasks, such as running applications, handling system operations, or processing data. High CPU usage can signal performance bottlenecks, while low usage may indicate underutilization of resources.
Developers should monitor CPU usage to optimize application performance, identify inefficiencies in code, and ensure system stability, especially in resource-intensive applications like data processing, gaming, or server environments. It is crucial for debugging performance issues, scaling infrastructure, and improving energy efficiency in cloud computing and embedded systems.
