Compressing Web Content
Linux Journal has a great article on compressing the content served by Apache. Since the vast majority of content being served is text (HTML, XML, etc) compression makes a lot of sense. Lower bandwidth, quicker downloads, the works. The real trick is to find the sweet spot between the level of compression and the amount of CPU you sacrifice to handle it. Once my new server is up and running (courtesy of Taurus) I will implement this ASAP.
