{{stub}}
Linux can bootup very slow or fairly fast depending on how its setup. Most [[Linux distribution]]s load allot of unnecessary stuff, that can be easily disabled.
==Boot loader==
Make sure the timeout is set to a low number 2 seconds is fine.

;Grub
*Edit: /boot/grub/grub.conf
**Modify line: timeout 2

;lilo
*Edit: /etc/lilo.conf
**Modify line: timeout 2

==Init processes==

;Disable unneeded processes
*Commands
** Gentoo
*** rc-update (console)
*** rc-config (console)
** Fedora/RHEL:
*** /usr/bin/system-config-services
*** /usr/sbin/serviceconf
*** /usr/sbin/ntsysv (console)
*** chkconfig (console)
** Red Hat:
***/usr/bin/redhat-config-services
*** /usr/sbin/ntsysv (console)
** Ubuntu / Debian:
*** bum (Boot Up Manager) (GUI)
*** /usr/bin/services-admin (GUI)
*** /usr/sbin/sysv-rc-conf (console)

;List of init processes
this list contains services from many different distributions, your system wont have all of them.

''* The remove recommendations, simply mean they are not required for normal operation. But if you want that feature to work, you need to enable it. For example if you want to use a printer, you need to enable CUPS.''
; Enable parallel loading
*Gentoo Linux
**Edit: /etc/conf.d/rc:
**Set: RC_PARALLEL_STARTUP="yes"

==kernel==
;Recompile [[Linux kernel|Kernel]] to fit your system
*Remove any unneeded components, you may be able to find the exact components required for your computer, and remove hundreds of unnecessary and unused ones.

==Make sure system is properly configured==
Things can load slower if you system has to test and guess settings. [[X windows]] loads slower if your host is not set.

;Make sure configs match
*Hostname (gentoo)
**for example hostname=tux networkname=tuxnet
**Edit: /etc/hosts
***Modify: 127.0.0.1 tux tux.tuxnet localhost
**Edit: /etc/conf.d/net
***Modify: dns_domain_lo="tuxnet"
**Edit: /etc/conf.d/hostname
***Modify: HOSTNAME="tux"
