独立服务器 CPU 频率最大化配置指南
独立服务器 CPU 频率最大化配置指南
看看 CPU 现在混哪种模式 前提条件 系统:Linux(Debian、Ubuntu、Proxmox 等都行)
权限:root
CPU:支持动态调频(Intel Xeon、AMD EPYC / Ryzen 等)
governor cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave:节能小绵羊(频率锁低,省电但废武功) ondemand:按需加速(要用时才升频,可能反应慢半拍) performance:全程高能(我们要的就是它!💪) 确认内核到底用的哪种驱动(Intel / AMD) cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
临时拉满性能 for cpu in /sys/devices/system/cpu/cpu[0-9]*; do echo performance > $cpu/cpufreq/scaling_governor done 重启后也保持高能 方案 A:最稳妥推荐 apt install cpufrequtils -y echo 'GOVERNOR="performance"' >/etc/default/cpufrequtils systemctl enable cpufrequtils systemctl start cpufrequtils 方案 B:systemd 自定义服务 # /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
