Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit X-Archives-Salt: 27aef2ec-933e-41f0-877f-d22449712adc X-Archives-Hash: e6c2a542e720da128ce3d65858978691 Hi, admin of a colo-center keeps complaining my server is going a little over power-limit (which they have set as ~120W per 24h/avg, while my server needs ~130-135W). So I need to find a way to save at least those 15W, or I will be moved to higher tarif (which means higher costs for server-housing). Before going hard(ware) way, I would like to try first all possible software solutions. What I tried up to now is cpufreqd, CONFIG_NO_HZ=y, and spindown. In addition to that I adjusted fan-speeds to a little lower values and turned off some unneeded peripherials (in bios). Is there anything else I could do? Any tips would be greatly welcomed...
