today's Facebook page is composed of a mix of sophisticated dynamic content, constantly updated with your latest timeline, your friends' status updates, notifications, online chats, third-party advertisements tailored to your interest, and so on.

While this complex mashup may be a result of careful design choices made by Facebook, for us, accessing Facebook is no longer as lightweight as used to be. For example, don't be surprised if opening your Facebook page on web browser involves more than a dozen TCP connections to different end points (e.g., Facebook CDN, Akamai, third-party advertisers, etc).
