The optimization of a website is also about testing the performance to determine what elements can be optimized to yield performance. With WP Speed of Light you can run several tests on the same page and open a comparison table. We’ve made an integration with Google speed test tool (free) to run detailed speed tests on various elements like:

  • First loading time
  • Second loading time
  • First byte time
  • Time to start rendering
  • Element served from cache in %
  • Elements compressed with Gzip in %
  • Percent on compressed images

WordPress database speed test and cleanup

The plugins and theme database queries can represent something important about WordPress’ speed. The database speed test may help you to determine problems with a theme or a plugin and fix some major performance issues. The database cleanup can be made automatically at a defined frequency in the PRO ADDON.

WordPress image compression

Images represent an average of 60% of the page weight so it’s a high priority in the optimization process.

WP Speed of Light includes an image compression quota with the plugin subscription, so you’re sure that the image compression works with all other WordPress optimizations!

  • Progressive image generation and loading effect

  • Almost invisible on fast connections

Cache preloading & DNS prefetching optimizations

The cache preloading is the process of generating a first version of the page cache automatically, so the first user who comes to the page after a cache cleanup won’t have to wait for the cache generation! It’s included in the plugin PRO ADDON. On the other side the DNS prefetching will preload DNS information of external domain links. For example, if your website is referring frequently to an external domain in hyperlinks, pre-fetching the DNS of this domain will load the page of this domain faster when a user click on it.
