I. Preface we all know that the tasks under Windows for each run are managed and viewed through Task Manager. So under Linux. Frequently used system performance analysis commands: Top [Displays information about processes currently being executed by the systems, including process IDs, memory usage, CPU usage, etc.] it dynamically takes a real-time view of the resource footprint of each process in the system

the CPU utilization of the entire Linux system by controlling how long the process is running and usleep. In order to reduce the CPU scheduling of the switching time, we make the running time for the system a clock interrupt time, that is, set total time of 100ms, running time of 10ms, idle time is 90ms. The program code is as follows: #include #include #include
CPU cache query tool in Linux In Linux, you can use the following tool to query the CPU cache: Method 1: $ Lscpu L1d cache: 32 K Method 2: $ cat /sys/devices/system/cpu/cpu0/cache/index0/size32K $ cat /sys/devices/system/cpu/cpu0
In Linux, for multi-core arm chips, CPU0 will take the lead in Bootrom code, booting the bootloader and Linux kernel, while other cores bootrom typically place themselves in WFI or WFE states when they are on. and waits for the CPU0 to give its CPU nuclear interrupt (IPI) or event (generally through the SEV Instruction) awakened. A typical startup process is show

In the Linux system can be cat/proc/cpuinfo to view the relevant information on the CPU, through processor can determine the number of logical CPUs, physical ID can determine the number of physical CPUs, through the CPU Cores to determine the number of cores per CPU, siblings and C
Under Linux, you can query the CPU cache using the following tools, for example:Mode 1:$ lscpuL1D cache: 32K Mode 2:$ cat /sys/devices/system/cpu/cpu0/cache/index0/size32K$ cat /sys/devices/system/cpu/cpu0/cache/index0/level1$ cat /sys/devices/system/cpu/cpu0/cac
Under Linux, the top tool can display the average CPU utilization (USER,NICE,SYSTEM,IDLE,IOWAIT,IRQ,SOFTIRQ,ETC.), which shows the utilization of each CPU. However, this situation may occur when the CPU utilization of each thread cannot be displayed, and the total CPU utiliz
