I am new to Proxmox, even new to running servers. I am documenting this for my own, use it in your own risk.

My Proxmox Cluster


Turn on/off machine

If machine is not in use, it’s better to turn it off. Machine can be turned on using Wake-on-LAN

crontab -e
@reboot /usr/sbin/ethtool -s enp2s0 wol g

Tune using powertop

crontab -e
@reboot /usr/sbin/powertop --auto-tune

CPU frequency scaling

Check if CPU frequency scaling is available

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

If it does, add a cron entry

crontab -e
@reboot echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1

Live long and prosper! :vulcan_salute:
