This parameter is 0 by default when viewed. What does 0 mean?

| tidb | 192.168.201.1:4000 | performance.max-procs | 0 |

To add, the test machine has only one tidb-server deployed, and no multiple tidb-servers are running on a single machine. Is the default value 0 when deploying one on a single machine?
