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...
