Quick Checklist

  • write valid HTML, JavaScript and CSS code
  • optimize your images, scale them down, combine them if possible (Photoshop Elements has some good features to preview images in various qualities)
  • compress all text output before sending it to the browser
  • combine multiple JavaScripts into a single file — the same is true for CSS
  • use CSS sprites for decorative images which allows you to reduce the number of HTTP requests
  • don’t use text for header images if you could write the text on a simple (reuseable) background image
  • employ caching on the server (for PHP and/or SQL requests) — RAM-based caches are best or use a disk cache for database requests which are not frequently modified.
  • use virtual hosts like img1.domain.com, img2.domain.com, img3.domain.com to allow parallel downloads of your images (these domains can point to your main www.domain.com directory tree)
  • use dedicated servers for static content distribution (such as lighttpd)
  • use caching/expiry headers for your static content so that they are loaded directly from the browser’s cache
  • setup mirror servers worldwide for your static content and output your HTML, JavaScript and CSS code dynamically with the name of the closest mirror server dynamically inserted through geo mapping
