Well, as far as I can see it’s not doing anything other than switching the CPU to lower performance states with less power consumption if there is less system load. That is something the linux kernel already does on its own if you use the “ondemand” cpu frequency governor which is activated per default on many distributions.
I expect that the “power saved since micromiser start” is nearly equal to what the linux kernel saves if left to its own. I would be very interested in a benchmark which compares a system fine-tuned with powertop and a micromiser system (also fine-tuned with powertop before to make equal starting conditions)…

I’m curious about this on my own server. It’s on some older hardware so it’s not as efficient as the newer stuff. I’d like an invite if possible.

Hi,

I certainly would like to be added to the trial. I have three servers in my home office ranging from a Asterisk Mini-ITX server (low wattage anyway) up to a Dual CPU Opteron server. All servers are on 24×7 so would love to reduce my power consumption a bit

@yungchin,

I have received an email from Miserware regarding their license terms. They have updated them and made them a little less onerous:

Several folks have asked about benchmarking against other power management software. With regard to benchmarking, we want to clarify the intent of the license. Our intent was not to preclude benchmarking altogether, but to ensure the measurement methodology is fair to all parties. More precisely, our lawyers told us to paste both permissions together:

“You are hereby authorized to disclose information regarding the performance of the MicroMiser software, (i) provided that such information is provided to you in a MicroMiser software report, or (ii) provided that such information is obtained using techniques approved in writing by MiserWare.”

The changes are retrospective to existing accounts as well as all new sign-ups.

Alan – it has many thanks. It claims its saving a steady 33%. I’m intrigued. I’ll leave my laptop on to see if I get 4 hrs instead of the usual 3. Many thanks for your help.

Hi David, no problem. I’ve sent another invite to your gmail account. Hope that one arrives.
