 You could also add a line to your ''/etc/rc.local'' file for instance to set the governor to //performance// at boot time: You could also add a line to your ''/etc/rc.local'' file for instance to set the governor to //performance// at boot time:
-  echo -n performance > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor+  echo -n performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor 
 + 
 +Another option is to create a Systemd Unit that does this for you. Example of an audio-setup Unit file: 
 +  [Unit] 
 +  Description=Prepare system for audio 
 +   
 +  [Service] 
 +  Type=oneshot 
 +  ExecStart=/usr/local/bin/audio-setup 
 +  RemainAfterExit=yes 
 +   
 +  [Install] 
 +  WantedBy=multi-user.target 
 + 
 +This will start ''/usr/local/bin/audio-setup'' at boot so you can add the aformentioned line regarding setting the CPU's to the //performance// scaling governor there, make the file executable, enable the Systemd service and start it. 
 +  echo 'echo -n performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor' | sudo tee /usr/local/bin/audio-setup 
 +  sudo chmod +x /usr/local/bin/audio-setup 
 +  sudo systemctl enable audio-setup 
 +  sudo systemctl start audio-setup 
 + 
 +The ''audio-setup'' script could then also be used to set up other things.
