Subject: scaling_cur_freq stays at maximum

I do experience regularly at my server that the values of /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq stays at maximum for all CPUs after few days or if the the load was high for a certain time. I'd expect a decrease of current frequency., or?

The system :
	Linux mr-fox 5.3.10 #5 SMP Sun Nov 10 11:40:48 CET 2019 x86_64 Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz GenuineIntel GNU/Linux
is running a hardened Gentoo Linux with vanilla kernel.

Attached are the compressed SVG graph showing the sysstat graphs of today and the kernel .config.
