This applies to gentoo linux and maybe others too. It lets all your startup apps start in parallel rather than one after the other so you are not sat waiting for some process to complete an i/o request or some such thing.
Ive been playing with initng (which is a sysinit replacement designed to do this) for a bit with only partial luck in getting it to work but with a nice speedup in boot/shutdown speed when it was. Im now annoyed to find that theres an option in /etc/conf.d/rc to use parallel booting with sysinit which has made my system equally fast if not faster too boot and shutdown. Ive not seen it in many guides so im not sure how many know about it. But i suggest you try it if u dont, it works great.
