      # Learning Objectives
      *After completing the work in this module you will be able to:*
      1. Optimize system performance by selecting a tuning profile that the `tuned` daemon manages.
      1. Prioritize or deprioritize specific processes, with the `nice` and `renice` commands.

      # Key Takeaways
      1. The `tuned` service automatically modifies device settings to meet specific system needs based on a predefined selected tuning profile.
      1. To revert all changes of the selected profile to the system settings, either switch to another profile or deactivate the `tuned` service.
      1. The system assigns a relative priority to a process to determine its CPU access. This priority is called the `nice` value of a process.
      1. The `nice` command assigns a priority to a process when it starts.
      1. The `renice` command modifies the priority of a running process.
