Just installing Ardour 6.9.
I am not a Ubuntu freak and do not understand this message:
!!! WARNING !!! - Your system seems to use frequency scaling.
This can have a serious impact on audio latency.
For best results turn it off, e.g. by choosing the ‘performance’ governor.
I have no idea what my system (Ubuntu 20.04.3) is using… what is frequency scaling? how/where should I choose a “performance governor”?
