Using the top or PS command will output PRI/PR, NI,%ni/%nice These three indicator values, what exactly is this thing? The approximate explanation is as follows:PRI: Process priority, which represents the priority that the process can be executed,

Linux under nice/renice command summary2010-03-30 12:58 1.1.1 Nice Command The kernel determines how much processor time the process requires, depending on the nice value of the process. The value range for the nice value is:-20 to 20. A process

1. Nice commandThe kernel determines how much processor time the process needs based on the nice value of the process. The value range for nice values is: 20 to 20. A process with a nice value of 20 has a high priority. A process with a nice value
