Hardware and Performance / Re: New to OPNsense - improving power consumption
« on: September 09, 2023, 11:17:46 pm »
There are several forum threads on power consumption.
One in particular recommended using powerdxx and playing around with the C states. Try here: https://forum.opnsense.org/index.php?topic=28033.0
But generally speaking, a firewall is unlikely to reach high C states because it will invariably be woken up by incoming traffic (= interrupts). Plus, certain NICS or NIC settings will prevent high C states (example: Intel 1G NIC, an i219 IIRC, will prevent high C states if you enable jumbo frames).
