さらばESXi、Proxmox VEへの道9 CPUの省電力
まずは、cpufrequtilsをインストールして、省電力状態を確認。
# apt install cpufrequtils
# cpufreq-info
Ryzen 2600を使っているんのでCPU0-11まで表示されるが、ざっくりとみると
analyzing CPU 0:
driver: acpi-cpufreq
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: 1.55 GHz - 3.40 GHz
available frequency steps: 3.40 GHz, 2.80 GHz, 1.55 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance, schedutil
current policy: frequency should be within 1.55 GHz and 3.40 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.55 GHz (asserted by call to hardware).
cpufreq stats: 3.40 GHz:100.00%, 2.80 GHz:0.00%, 1.55 GHz:0.00% (1)
一往1.55まで下がるようになっているようだが、下がったためしはない
