Here is a quick tip to reduce the page load time.
As you know for each HTTP request there happens three-way handshake. So if you are fetching content from external objects and showing on page, it will be quite helpful to turn on HTTP keepalives for external objects. Otherwise you add an extra round-trip to do another TCP three-way handshake and slow-start for every HTTP request. If you are worried about hitting global server connection limits, set the keepalive timeout to something short, like 5-10 seconds. Also look into serving your static content from a different webserver than your dynamic content. Having thousands of connections open to a stripped down static file webserver can happen in like 10 megs of RAM total, whereas your main webserver might easily eat 10 megs of RAM per connection.
