The "Performance Mode" option is not available on all systems as it comes down to whatever powerprofilesctl is able to read from the UEFI on your motherboard. Many workstation and server-grade motherboards have just two settings available for the OS:
- Use what's needed when it's needed (active processing)
- Use as little as possible because the system idles most of the time (passive processing)
"Balanced" is generally sufficient for most desktop situations but, if you really want to change the setting, you can do so in the Terminal with this command:
powerprofilesctl set performance
Notes:
- Setting the power profile to something that is not displayed in the Gnome Control Centre can result in the window failing to open.
- There is no guarantee that
powerprofilesctl will be able to set your machine to "Performance Mode" if the UEFI does not actually have this mode.
- On some Zen1 and Zen2-based processors, changing the profile to an unsupported value has resulted in NUMA-related issues, where performance actually degraded. I do not know if this will affect your processor. However, in the event that you see degraded performance as a result of the setting change, a reboot usually clears up the mess.
