I am not at my EnOS box right now (and I don’t have cpupower installed) so I cannot check but did you look into /etc/default/cpupower to see if some variable could be set to performance?
The configuration file for cpupower is located in
/etc/default/cpupower. This configuration file is read by a bash script in/usr/lib/systemd/scripts/cpupowerwhich is activated by systemd withcpupower.service. You may want to enablecpupower.serviceto start at boot.
EDIT
You could try this: in /etc/default/cpupower change the following line:
#governor='ondemand'
to
governor='performance'
Then enable and start cpupower.service in one go:
sudo systemctl enable --now cpupower.service
Reboot and check.
