You can speed up the booting process a lot by disabling the services you do not need. Another advantage of disabling unwanted services is that you can free up a lot of RAM. Fedora has a utility to make this very easy. In other distros you will have to edit the files in /etc/init.d folder.
First run the ‘Service Configuration’ utility.
KMenu > Administration > Server Settings > Services Service Management
Or run ‘system-config-services’
Then disable all the services that you will not need. For more information on what to disable/enable here, go to Services in Fedora 7. That should give you an idea about which all service must be enabled.

After all configuration is done, click ‘Save’. You will notice the difference on the next boot.
