Update:
From tip and tweaks plug post, Intel newer CPU run with P-state driver, it is sensitive. The workaround to disable Intel p-state driver works.
The CPU runs at low frequent 800Mhz.
I suspect dir cache plug spike CPU, so CPU are not able to run at base frequent. then I disabled dir cache plug, but the problem is persisted.
I compare electricity consumed when enable or disable Intel P state driver, they are almost the same. This is unbelievable if CPU keep running at high frequency.
then I use cpufreq-info cli to check, finds current CPU frequency is expected at 800MHz. watch command seem incorrect.
But one more issue, if I uninstall tip and tweaks plug, then CPU governor set to performance. I do not know what is default value, but I think for most users, we want to save power at this moment.

analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4294.55 ms.
hardware limits: 800 MHz - 3.80 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 800 MHz and 3.80 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Unraid OS Trial
Version 6.10.0-rc4
CPU: Intel G5420
New to unraid, I found my machine consume two times power than ubuntu, even all disks already spin down.
After check, I found the frequent of most CPU cores high to 3800, but all 800 for my CPU at low load. All VMs and container stopped.

I installed fix common problem, no issue reported.
I installed tips and tweaks, CPU already set to power save mode. I tried performance or schedule, no different. also tried to reboot it.
