Performance improvements for 4

Optimizing the page load of a WordPress website is not an easy task.

The first think you need to do is to monitor your page load indicators. I usually test my websites with 4 well known online tools :




Results on GTMetrix


Results on




Pingdom tool results



Google Insight Results

With this tool, I got a 87/100 for desktop, 74/100 for mobile speed and 91/100 for the user experience.

There’s room for improvement, in particular to reduce the size of the above-the-fold content.


Tools and techniques used

It took me honestly days of iterations and tests to get those results. I could probably have been much faster if I had followed the quite simple steps described below.

Note : My website is hosted by a french host named Planet Work on a virtual server with the following characteristics : Linux/Apache/MySQL/PHP, 1000 Mo of cache memory, CPU 1200 MHz.


Here are the key points that have been decisive for my performance improvements :

1) I use the free Total Cache plugin with the following settings :

  • Page cache : Disk Enhanced
  • Minify CSS and JS enabled in manual mode
  • Database Cache : Enabled with disk method
  • Object Cache disabled
  • Browser cache enabled
  • CDN enabled

2) Almost all external ressources (CSS, JS, images, icon fonts) are hosted by a CDN (Rackspace) which is located close to most of my visitors (US based).

3) Images below the fold are not beeing loaded on page load. I use the excellent free Unveil Lazy load plugin for that.

4) Videos in iframes like YouTube or Vimeo are loaded on demand, triggered by a click. I use a the free plugin lazy load for videos for that.

5) All Images have been compressed

Hope this will help!

    Thanks, Nicolas, for your work!
    And your last update was great, it eliminated need for child theme the almost 100%. I could set all under “Customize”.
    Also, it is fast! Got 96/90 at second try (just enabled caching & optimizaton plugins).
    Thanks again – for design, for speed and for listening and implementing features.
