Steve Souders's web page performance best practices

Steve Souders (Yahoo!) gives a great presentation about web page performance. The 14 best practices are

1. Make fewer HTTP requests
2. Use a CDN (Content Delivery Network)
3. Add an Expires header
4. Gzip components
5. Put stylesheets at the top
6. Move scripts to the bottom
7. Avoid CSS expressions
8. Make JHS and CSS external
9. Reduce DNS lookups
10. Minify JS
11. Avoid redirects
12. Remove duplicate scripts
13. Configure ETags
14. Make AJAX cacheable

Many of these seem obvious at a gut level and the presentation gives detail about why at a technical level they are so.
