10 More Rules for Even Faster Websites

Thu, 05/01/2008 - 14:30 — Todd Hoff

80-90% of the end-user response time is spent on the frontend, so it makes sense to concentrate efforts there before heroically rewriting the backend. Take a shower before buying a Porsche, if you know what I mean. Steve Souders, author of High Performance Websites and Yslow, has ten more best practices to speed up your website:

Split the initial payload

Load scripts without blocking

Don’t scatter scripts

Split dominant content domains

Make static content cookie-free

Reduce cookie weight

Minify CSS

Optimize images

Use iframes sparingly

To www or not to www

Sadly, according to String Theory, there are only 26.7 rules left, so get them while they're still in our dimension.
