14 rules for fast web pages

Posted on | Mayo 11, 2007

Steve Souders of Yahoo’s "Exceptional Performance Team" gave an insanely great presentation at Web 2.0 about optimizing website performance by focusing on front end issues.

This is a big presentation, with a lot of data in it (a whole book’s worth apparently), but half way through he boils it down into 14 rules for faster front end performance:

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