Issue/Bug Description:

as per konkor/cpufreq#48 and http://konkor.github.io/cpufreq/faq/#irqbalance-detected

irqbalance is technically not needed on desktop systems (supposedly it is mainly for servers), and may actually reduce performance and power savings. It appears to provide benefits only to server environments that have relatively-constant loading. If it is truly a server-oriented package, then it shouldn't be installed by default on a desktop/laptop system and shouldn't be included in desktop OS images.

Steps to reproduce (if you know):

This is potentially an issue with all default installs.

Expected behavior:

n/a

Other Notes:

I can safely remove it via "sudo apt purge irqbalance" without any apparent adverse side-effects. If someone is running a situation where they need it, then they always have the option of installing it from the repositories.
