i have got a question concerning a new IPFire-build i am configuring right now. The hardware used is an Intel i3-9100 CPU, 16GB DDR4, a Gigabyte B365M-Mainboard and four Intel Gigabit nework cards.
I have noticed that the clock speed of my CPU does merely drop, even if there is just a very low usage. This means, at e.g. 1-5% load, the clock speeds of all four core stay at 4100-4200 Mhz with little drops to 3800 Mhz, even tough the idle clock rates should be around 1500-2000 Mhz.
This leads to an unnecessary power consumption.
In my old IPFire-build (Intel Celeron J1900 quad core) i had nothing to do to get the cores to their idle frequency, this worked automatically.
As i did some research, the “cpufreq-utils” should be installed automatically when using IPFire >2.x, but this is not the case in my build, since the package is visible as “not installed” in pakfire.
As i do not want to mess up my new build i want to ask, which is the best way to achieve idle clocks? Install the cpufreq-utils by using pakfire and setting the govenor to e.g. “on demand”?
Thank you very much in advance for your help and your time!
