Thanks for posting this. I was able to cut ~10-12 w by simply switching to ondemand. Granted my system is above a lot of what is posted but the Proxmox server (14 core w/ 128 GB of RAM) is running my firewall (with 2 - 10Gbps interfaces), a TrueNAS server with 16 TB of storage, frigate for 3 HD cameras, etc. Idle load is about 50w. Operational used to be slightly over 100w and now it is sitting at 90w. I’ll take a 10% improvement for flipping a few settings. Thanks!!!
The config change was a bit after noon on 15 Nov. Initially I did powersave but the average from ondemand is nearly the same so seems like the better choice for my system.
