Recommendation: CPU frequency scaling x86 Fujitsu Futro S920

[Underworld]

Hi,
I have Fujitsu Futro S920 running one of the latest snapshots. It seems that the default scaling governor is schedutil. My question is if that's the recommended scaling governor for x86.
The whole saga started with me measuring the power consumption of another S920 running proxmox, which was using performance and gave results of around 11-12 watt/hour. I change that to conservative and the consumption dropped to 8 watt/hour.
Then I measured my OpenWrt S920 and saw 11-12 watts consumption as well, so I started digging what is the recommended governor, as I believe the consumption is a bit high ( at least when I compare to proxmox.
So what would be your recommendation? Below some system data.
Thanks

Why dont you measure "performance"?

[frollic]

and what scaling_governor value did the proxmox box have ?

[Underworld]

Thanks for the replays. Proxmox was on "performance" and had 11-12 Watt consumption, I moved it to "conservative" and it dropped to 8 Watts.
I will test "performance", just a confirmation: to set it up correctly I need to do:

echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
echo performance > /sys/devices/system/cpu/cpufreq/policy1/scaling_governor
echo performance > /sys/devices/system/cpu/cpufreq/policy2/scaling_governor
echo performance > /sys/devices/system/cpu/cpufreq/policy3/scaling_governor

"Ondemand" should be avoided right?

[frollic]

I could imagine ondemand working like a car engine, if you do a kick down, it'll rev up, but there's a slight delay.

I have tested ondemand and performance. It seems that the power consumption is almost the same schedutil=ondemand. and "perfomance" +0.5 Watt/hour. I will leave it on "performance".
I will check the bios settings on both min pcs to see if there are any differences.
Thank you

I just realized that I am measuring apples with bananas. I have installed a dual NIC on my OpenWrt S920 and the proxmox one doesn't have that. On top I have USB WiFi dongle on the Openwrt, hence the difference in the power consumption - I would guess.
