Quick performance tip for Ubuntu Edgy and Feisty users:
Edit your “/etc/hosts” file
sudo gedit /etc/hosts
You should see something like this

Now, add the following lines
127.0.0.1 localhost onlyubuntu
(Replace “onlyubuntu” with your hostname)
Save and exit the file.
Now your applications launch should improve.
