14 Rules for faster website response

Some people from the company attended the Web 2.0 conference some time ago and came back to share some with you. One of them was "14 Rules for accelerating website response". steve Souders, former Yahoo Chief performance officer, has now switched to Google. Some simple front-end page optimization will increase your website response by 40%, it's exciting!

The rules are as follows:

Make fewer HTTP requests (Minimize the number of HTTP requests)
Use a CDN (image, parallel download)
Add an Expires header (using browser cache)
Gzip components (compressed download content)
Put CSS at the top (avoid repeated page rendering)
Move js to the bottom (preferentially load the page)
Avoid CSS expressions (avoid CSS operations)
Make JS and CSS external (share JS and CSS as much as possible)
Reduce DNS lookups (Domain Name level should not be too deep)
Minify JS (compressed JS capacity)
Avoid redirects (do not jump through browser)
Remove duplicate scripts (avoid repeated code)
Turn Off etags (disable entity tags)
Make Ajax cacheable and small (cache is also required when using Ajax)
