Performance tip for Ubuntu Edgy and Feisty users

One user suggested the following tip to improve the applications launch performance.
$ sudo gedit /etc/hosts
You should see something like this:
127.0.0.1 localhost
127.0.1.1 user
(and if your in Feisty, some lines about IPV6 also)
Now, edit to:
127.0.0.1 localhost user
127.0.1.1 user
(Replace “user” with your hostname).
Save and exit the file.

Now your applications launch should improve.
