Our centos system with AMD Cool and Quite activated seems to be slower under load than without cpu scaling.
Another point is running a vmware server on such a host – will this feature work probably?
Follow these steps to turn it off, just to make sure 😉
To immediate turn off on running system:
should return “ondemand”
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
to deactivate this feature
should show the full cpu clock speed
To make these changes permanent:
to see available options
GOVERNOR= # default setting
this makes the change persistent to next reboot
