獨立伺服器 CPU 頻率最大化配置指南
獨立伺服器 CPU 頻率最大化配置指南 看看 CPU 現在用哪種模式 前提條件 系統:Linux(Debian、Ubuntu、Proxmox 等都行)
權限:root
CPU:支援動態調頻(Intel Xeon、AMD EPYC / Ryzen 等)
governor cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave:省電小綿羊(頻率鎖低,省電但沒力) ondemand:按需加速(要用時才升頻,可能反應慢半拍) performance:全程高能(我們要的就是它!💪) 確認核心到底用哪種驅動(Intel / AMD) cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
暫時拉滿效能 for cpu in /sys/devices/system/cpu/cpu[0-9]*; do echo performance > $cpu/cpufreq/scaling_governor done 重啟後也保持高能 方案 A:最穩妥推薦 apt install cpufrequtils -y echo 'GOVERNOR="performance"' >/etc/default/cpufrequtils systemctl enable cpufrequtils systemctl start cpufrequtils 方案 B:systemd 自訂服務 # /etc/systemd/system/cpu-performance.service [Unit] Description=Set CPU governor to performance After=multi-user.target [Service] Type=oneshot ExecStart=/bin/bash -c 'for cpu in /sys/devices/system/cpu/cpu[0-9]*; do echo performance > $cpu/cpufreq/scaling_governor; done' [Install] WantedBy=multi-user.target systemctl daemon-reexec systemctl daemon-reload systemctl enable --now cpu-performance.service
