I beleive you can do more, for example if you start looking:
- DNS (I don't know too much about this though)
- How the web server handles the requests (I saw a post here on HN about this recently but can't find it where MS/Google change some deep settings to improve loading time)
- Preloading pages by guessing users next page choice
All are quite difficult to execute however and provide diminishing returns over making sure you have all the fundamental things set up correctly.
