As someone else also pointed out, in an idle system perhaps you won't see any significant power savings when reducing the clock frequency. I mean, idling somewhat slower (eh...) more or less only affects the interrupt handlers. I'd measure power under full CPU load with hw.setperf set to 100 and 0 respectively and see what happens. Also, even if what Amit points out is true, that all cores wake up at each rrticks_init (and assuming that there's an improvement to be made there), that would be true even in high performance mode so would most likely not affect the relative difference in power consumption between the two modes of operation.

Re: Question about apmd power savings
If going from 1.3GHz to 800MHz saves .5 watts, the power supply isn't the most efficient, I'd say. You ought to see several watts, though less than 10, at a wild guess. Of course, your kill-a-watt meter might be off, too. I saw one that was +/- 20% of its crate mates, so while I think the product is neat, I'm not sure of their build quality.

you could replace that 3.5" disk drive with a 2.5" one and save some more that way..

Sorry Joe, I'm not subscribed to misc@, marc.info is ro, I didn't see your message. I worked on K10 freq scaling for my laptop, indeed, it doesn't help much in terms of measurable power savings.. not as much as I had hoped it might. Playing with voltage settings may have helped, but it seemed risky.. no other implementation messages with it either. The effects are more noticable on laptops, but for desktops/workstatons, it's not really worth enabling apmd, just make sure you have decent cooling. -Bryan.

Thanks for the explanation. I can't complain. The box runs at 35 watts, which is a significant reduction in energy usage over my previous home server.
