For example, system load (uptime), system memory usage (free), and system CPU usage (vmstat. Therefore, you can use this command to view the sources of system load in a comprehensive manner. At the same time, THE top Command supports sorting by different columns to facilitate searching for processes with the most memory usage and processes with the highest CPU

System callsThe process has two modes of operation: User state and kernel state. The process is usually in the user state, when the CPU and memory can be used, and when the process needs to operate on the hardware peripherals (such as reading disk files, sending network data), it must switch to the kernel state, when the kernel-state task is completed, the process is then cut back to the user state.Because the system call involves the process from the user state to the kernel state of the switch
