This isn't a problem and I'm not complaining, I'm just a bit curious
as apmd didn't save me as much power as I hoped for. I noticed that
apmd couldn't throttle my cpu in 4.9-RELEASE (amd64). However, since
March 2011, -CURRENT recognizes the K10 cpus, so I wanted to try it
out apmd on my HP Microserver. So I upgraded my system from
4.9-RELEASE to a recent -CURRENT snapshot. When I run "apmd -C"
hw.setperf gets set to 0 and the hw.cpuspeed gets set to 800 MHz. That
was expected. I attached a Kill-a-Watt meter to my system to see what
kind of power savings I would experience with apmd enabled. I think my
expectations were a bit too high. I was only saving .5 watts when my
cpu was throttled down to 800 MHz from 1.3 GHz. I haven't seen many
posts on this subject, so I was wondering if the power savings of .5
watts sounds normal, or if something is wrong on my end.
