Disabling unused daemons to speed up your boot sequence

Filed under

Many Linux distros usually start a lot of daemons when booting, resulting in a long wait before you can get to work after powering on your machine. Some of those daemons are rarely used (or even not al all) by the majority of users. This tutorial describes how to disable unused or rarely used daemons in a proper way, resulting in faster boot sequences and less CPU load.

You can list all processes that are started when booting to graphical mode with the following command:

When running a text-mode system, you will usually boot to runlevel 3. To see the processes that are started at boot time on these systems, use this command:
