WordPress Speed Testing & Performance Comparison

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 WebPageTest API (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

Database Speed Test and Cleanup

The 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 CDN Integration

  • Cloudflare CDN
  • MaxCDN
  • KeyCDN
  • Varnish Cache
  • Siteground SuperCacher

WordPress Image Compression

Images represent an average of 60% of the page weight so it's a high priority in the optimization process. The image compression is the process of applying an invisible image compression and reduce image size by up to 80%. 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!

Cache Preloading & DNS Prefetching

The cache preloading is the process of generating a first version of the page cache automatically, so the first user that 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 pre-load DNS information on 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.
