Have you guys thought about installing mod_gzip
on your machine?
mod_gzip is an Apache module that will compress your outgoing data using gzip before sending it to the browser. HTML pages (the bulk of your site's traffic) typically get compressed 3-10 times their original size. This would mean substantial bandwidth savings for you, and faster page loading times for us.
Most post-1999 browsers support gzip encoding. As for browsers that don't, they won't send "Accept-Encoding: gzip" in their HTTP headers, so mod_gzip will not compress the data sent to them.
