rr: Warning: Your CPU frequency governor is 'powersave'.  rr strongly
    recommends that you use the 'performance' governor.  Not using the
    'performance' governor can cause rr to be at least 2x slower
    on laptops.

    On Fedora-based systems, you can enable the 'performance' governor
    by running the following commands:

    $ sudo dnf install kernel-tools
    $ sudo cpupower frequency-set -g performance
