We're building some pretty fat sites right now. The average site is over 2MB, which is ridiculous – and in many countries very expensive.

A lot of that is just unnecessary bloat things like images that are too big, misbehaving third-party scripts, and heavy JavaScript frameworks.

But it's not such a huge problem that it can't be solved. Developers need to build with care to make sure the sites they produce are lean and fast.

Here are six things all developers should be doing to improve the performance of their websites…

  1. Compress your images and serve them at correct size
  2. Minify and compress all your HTML, CSS, and JavaScript
  3. Limit the use of heavy JavaScript. Render as much as you can on the server and use JavaScript to sprinkle on enhancements
  4. Optimise for the critical path so that your content appears as quickly as possible
  5. Start familarising yourself with HTTP/2 because that changes so many things
  6. If you're going to use something like Bootstrap, be sure you remove all the unused CSS in a build process. There's a ton of unnecessary bloat.
