Power Saving
Thursday, July 3rd, 2008I was poking around yesterday reading about how to save energy with computers. It turns out that, under linux at least, you can do a huge amount to save power just by changing some kernel options.
Dactyl isn’t a powerful computer, the processor is an 800 MHz VIA C3. However, with some of the tweaks I just did, it now hangs out pretending that it’s a 400 MHz computer right up until it has to serve a web page or actually do something. That saves half of the energy it would have otherwise been using!
Side note: for dactyl, this isn’t that impressive… it’s like 3 watts instead of 5 watts.
