14 Rules for faster-loading Web Sites.

These 14 rules came from Steve Souders’ book High Performance Web Sites (O’Reilly Media 2007).

Rule 1 – Make Fewer HTTP Requests
Rule 2 – Use a Content Delivery Network (CDN)
Rule 3 – Add an Expires Header
Rule 4 – Compress Components with Gzip
Rule 5 – Put Stylesheets (CSS) at the Top
Rule 6 – Put Scripts (JavaScript) at the Bottom
Rule 7 – Avoid CSS Expressions
Rule 8 – Make JavaScript and CSS External
Rule 9 – Reduce DNS Lookups
Rule 10 – Minify JavaScript
Rule 11 – Avoid Redirects
Rule 12 – Remove Duplicate Scripts
Rule 13 – Configure ETags (turn off)
Rule 14 – Make AJAX Cacheable and small

The Performance Golden Rule states that developers should “optimize front-end performance first, because that’s where 80% or more of the end-user response time is spent”
