Just wanted to find out other people's impressions of the power consumption/power efficiency of computers running FreeBSD vs other OSes. Based on my limited testing(possibly flawed), my impressions is that FreeBSD has ended up not faring so well vs Windows7 and Ubuntu, and wanted to see if other people have experience the same or suggest any tweaks I can make.
Built a rig with following components:
The above setup is running headless, so no keyboards/mice/display devices are connected. For testing purposes, no HDDs are connected internally(to be used for RAID later)
I tested with the following OSes:
I realise that FreeNAS is only a derivative of FreeBSD and haven't tested with the latest version of vanilla FreeBSD yet,but I reckon it'll still be similar to the figures I'm getting with FreeNAS.
Is FreeBSD just known as not so power efficient? I would have assumed that it would be better than a bloated beast like Win7....
Would appreciate any thoughts.
Built a rig with following components:
- Intel G620 CPU (Sandybridge)
- Intel DH67GD motherboard
- 2 x 2gb Kingston RAM
- Seasonic 330W power supply

I tested with the following OSes:
- FreeNAS 8 (based off FreeBSD 8), with powerd running - 31W
- FreeNAS 7 (based off FreeBSD 7), with powerd running - 31W
- Windows 7 Ultimate - 23W
- Ubuntu Desktop 10.04 - 28W(with display/keyboard/mouse connected). Believe this is <25W with the peripherals disconnected.
