I you are concerned about resources, wouldn't you be better off getting a low-power machine, with SSD disks? There are machines out there that eat around 10W and get the job done (dependeing on the job of course); and SSD doesn't need to spin down. > I cannot share the full dmesg for security reasons Bullshit.
