There seems to have been some (stupid) change to the Linux kernel, where the CPU are stymied to a low power setting.

running cpufreq-info I get: The governor "ondemand" may decide which speed to use

I see that I can change one core like this: sudo cpufreq-set -c95 -g performance

But how do I set ALL cpu cores to PERFORMANCE permanently (persist across reboots)?

vi /etc/default/cpufrequtils

make like this: GOVERNOR="performance"

then:

sudo systemctl restart cpufrequtils

check with this:

cpufreq-info

I'm not sure if it'll work on x86 computers, but it does work on the RaspberryPi:

echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
