One: Among the data that appears after entering top in bash, the ones that are easy to understand are currently
1. The num total in task: means there are num processes in total; num running is the number of running processes; num sleeping is the number of processes that are sleeping (not yet allocated to a time slice); num stopped is the number of processes stopped; num zombie is the number of zombie processes;
2.top: The three values after load average represent the system load rate within 1 minute/5 minutes/15 minutes, the smaller the better;
3.Cpu: num us indicates the percentage of user occupied; num sy is the percentage of cpu occupied by the system; num id (idle) is the percentage of idle resources; (resource refers to cpu)
4.KiB Mem: num total represents the total amount of physical memory, such as 8g memory (in M); num used physical memory already in use; num free physical memory; num buffer/cache cache size;
5.KiB Swap: num total represents the total amount of virtual memory. The virtual memory set in the root windows system is a reason, and it is almost meaningless if the memory has more than 8g of virtual memory;
