In order to get the best performance from your processor for audio work, you need to set the CPU mode to 'performance'
To Set Temporarily
To temporarily change this setting which resets upon reboot, run this command in your console:
sudo /usr/bin/cpupower frequency-set -g performance
This will set your CPU to it's maximum rated speed. This will draw more power, and if you are using a laptop, it will drain the battery quicker.
To Set Permanently
If you wish to make this change permanent, you need to create a special text file.
Using your console text editor of choice create the following file (for this example, I will use nano which is pre-installed with openSUSE).
sudo nano /etc/systemd/system/cpupower.service
Copy and paste the following text into the newly created file:
[Service] Type=oneshot ExecStart=/usr/bin/cpupower frequency-set -g performance
Then save and close the file (in nano it's ctrl + o then enter to save. To exit press ctrl + x
Then run the following command:
sudo systemctl daemon-reload
systemctl enable cpupower.service
