Power Saving Software for Linux
MiserWare MicroMiser is an intelligent software power management solution for x86 servers, laptops, and PCs running Linux. MicroMiser automatically optimizes a system to use energy more efficiently without compromising performance or availability. The MicroMiser Power Management Daemon (see below) when installed on a server, laptop, or PC, matches the energy consumed by the system to the load on the system automatically. MicroMiser typically lowers total system energy use by 10-35% even when a system is 100% utilized. MicroMiser also tracks the energy saved for use in estimating cost savings and carbon emission reductions.
I have installed it on 4 PCs so far and all seems to be fine. Installation is very simple as the download is in a deb or rpm package.
I am especially interested to monitor any battery-life performance improvements on my laptop computers and any savings to my always-on–home-server will be most appreciated. The site has downloads for most of the recent Ubuntu, Debian, Fedora, RHEL, and SLES distributions.
It appears to work on VIA C7 chips, and Intel Core2 8X00 and mobile T5000 series. Well, it does for me.
As you can see above, the company claim between 10 and 35% power savings with this software which is definately not to be sneezed at in these frugal times.
