It is acceptable if the number of active processes per CPU is not greater than 4.
If the number of active processes on each CPU is greater than 5, the system performance problem is serious.
You can also use the vmstat command to determine if our system is too busy. If it is determined that it is very busy, consider whether to change the server or increase the number of CPUs. Summary:
If r is often greater than 3 or 4 and the id is often less than 50, it indicates tha
