Your heaviest load times are going to be either the
JavaScript itself or CSS files in the head section. This is
due to the fact that when JavaScript or CSS is being parsed
by a browser it typically just uses one connection to do so
where as other elements in the body section load through
multiple connections. In short all attention is focused on
parsing the JavaScript and the other elements have to wait
until the JavaScript is parsed to render.

That is why doing this sort of thing in Web pages is
notoriously poor:
</p>
<p class="code">
<script src="blah1.js"
type="text/javascript"><br />
</script><br />
<script src="blah2.js"
type="text/javascript"><br />
</script><br />
<script src="blah3.js"
type="text/javascript"><br />
</script>
</p>
</body>
