Today ran a very time-consuming bulk insert operation. When using the top command to view the CPU and memory usage, the CPU was checked by 120%. Never noticed before. By pressing 1 on the big keyboard in the case of top, the number of cores viewed by the CPU is 4 cores.

By looking through the Web, the top command shows the total number of CPUs your program consumes, which means that if you are a 4-core CPU, the maximum CPU occupancy is up to 400%,top and all usage rates are added together.
