this is a simple mod that you can use to compress your website using gzip which will reduce your bandwidth. this is dead easy to setup in ubuntu. to do so, log into your webserver via ssh or locally if you dont run it headless like me. then enabled the deflate mod by typing the following command:

sudo a2enmod deflate

and then reload apache by typing in:

sudo /etc/init.d/apache2 force-reload

thats it… dead simple, speeds up your website, and saves you a few bucks on bandwidth.
