Changing user priority

Changing user priority

The priority setting determines the scheduling priority for the user's processes: the greater the value, the higher the priority.

To change the priority for an account, use this command line:

usermod -x "{nice value}" username

Processes using traditional scheduling have priorities 0 (low) to 127 (high); processes using real-time scheduling have priorities 128 to 255.

To change the system default used for account creation, use this command line:

usermod -D -x "{nice value}"
