Hokay, a good way to speed up your website is to make JS/CSS external, as in files and use a CDN
well we don’t have money for CDN’s but we can do some naughty things
you can use

http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js

for jquery, and just 1.3.2 (latest) with your version
you will have a quick access to the qjuery library, no bandwidth used, and a 100% uptime

more tricks soon
