1.Disable unwanted services.

This will definitely speed up your system to an extent.But dont end up disabling essential services(this could do you harm rather than speeding up your system).Here are some suggestions

a.First boot  – This is required only for the first boot after installation and hence can be disabled after that.

b.Cups  -These should enabled only if  you have CUPS compatible printer that works in Fedora attached to your .computer directly or through a network connection.

c.Httpd – This is Apache HTTP web server.It can be disabled unless you are trying some web development activity .

d.Irda – IrDA support infrared communications between devices (laptops, PDA’s, mobile phones, calculators, etc). This should not be enabled for most users.

e.Isdn – This is another form of internet connect service/hardware. Unless you have an ISDN modem disable this.

f.Mdmonitor – Is used for checking  Software RAID or LVM information.Not essential

There are more to mention.Try out that yourself

2.Disable SElinux.

Selinux is for security enhancements and may be disabled in your home desktop.To disable SElinux you should modify the /etc/selinux/config.

After making changes as given below reboot your system.

# cat /etc/selinux/config

SELINUX=disabled

SELINUXTYPE=targeted

SETLOCALDEFS=0

Now enjoy your fedora at greater speeds….
