6 Ways to Make Ubuntu Fast

6 Ways to Make Ubuntu Fast

1. Remove Network Manager if you do not need it �sudo apt-get remove network-manager�. If possible give yourself a static IP in /etc/network/interfaces like so:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.150
netmask 255.255.255.0
network 192.168.1.100
broadcast 192.168.0.255
gateway 192.168.1.1

Having a static IP helps with boot time as your machine doesn�t have to communicate with the router/dhcp server as much to obtain an address.

2. Also remove firestarter or whatever graphical firewall frontend you�re using.Learn to control iptables at boot up and shutdown. It�ll be much snappier.

3. Install bum, �sudo apt-get install bum� and run it with root access. Shut off all unnecessary services. If you�re not sure about a service research it before shutting it off. Also, install sysv-rc-conf. Run the application as root. This will allow you to control, in an easy way, what services start at which run level. It�s like bum, but more detailed. Be very careful with which services you are removing from which run-level. If you don�t know what you�re doing here, research it or don�t touch it. After you do this you may want to reboot to make sure you didn�t break anything.

4. Turn off usplash in grub. (Mind you, you�re bootup won�t be as pretty as the splash will go away).

• vim /boot/grub/menu.lst
• on the kernel line delete the words �splash� and �quiet�
• Reboot to see the changes.

5. If you have a dual core processor, you can decrease your boot time with concurrency.

• sudo vim /etc/init.d/rc
• and find the line CONCURRENCY=none and change it to:CONCURRENCY=shell
• Reboot to see the changes. (tired of rebooting yet?)

6. Remove some TTYs

I could easily do this by editing /etc/inittab and then commenting the extra TTYs there. With the new upstart mechanism in place, things are a little different.

You have to edit /etc/default/console-setup file. This file defines how many ttys should you get.

Change ACTIVE_CONSOLES=�/dev/tty[1-6]� to the number of consoles you want. Lets say, 3 ttys, then change it to �/dev/tty[1-3]�.

And then goto /etc/event.d/ and change the ttyx files that you DONOT want. Edit them and comment lines starting with �start on runlevel�. So, in this case, you�ll comment the start line in tty4..tty6 files.

Rebooting shoud minimize the number of consoles for you. Worked for me!! Good luck, NOTE: Even though you�ve reduced the tty number, X is still on Alt-F7. Again, go ahead and reboot to make sure you didn�t break anything.
