Make Your Linux Boot Faster

Make Your Linux Boot Faster

Steps that can make your Linux system boot faster.

Step 1 :
Decide on the unnecessary services and stop them. Try to stop them using the following commands :

chkconfig ip6tables off
chkconfig setroubleshoot off
chkconfig vmware off
chkconfig bluetooth off
chkconfig sendmail off
chkconfig yum-updatesd off

Step 2 :
If the loop-back device is not needed, stop it to save 1 second . Add
ONBOOT=no in its ifcfg file.


Step 3 :
* Kill all splash screens,
* Grub splash (the line that has 'splash image' should be commented in grub.conf),
* Boot splash (edit/ etc/ sysconfig/ init and say No color there) and
* KDE splash (goto the control center and stop it ).

Normally kernel has lots of unnecessary modules that get loaded when the machine starts. Even if you use only the Ethernet, but still the kernel loads the wireless, Blue tooth and router related modules. Disable them or recompile the kernel.

This should save you more than 30 seconds each time u boot your machine. You can tweak your system as per your requirements & save some boot time.

Note: This is configured for PC which has 512 RAM , an Intel dual core processor with RHEL5.1. but holds good for all most all configurations. - Admin (CosmoCyber)
