Speed optimization with WordPress and browser caching
WP Speed of light for WordPress comes with a lot of optimization systems such as cache system: it generates more static content (HTML) therefore reducing the number of database queries required to load the page. Plus, you have the possibility of storing the major part of the heavy page resources (like images) in the browser cache. And you can clean it when you want! Full optimization list:

WordPress speed optimization testing with Google Speed test
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.
Speed optimization with WordPress CDN Integration
A CDN (Content Delivery Network) integration is available. It is compatible with all the major CDN on the market including Cloudflare, Amazon Cloudfront, MaxCDN, KeyCDN and others. Plus, there’s a specific automatic cache cleanup for:
- Cloudflare CDN
- MaxCDN
- KeyCDN
- Varnish Cache
- Siteground SuperCacher
WordPress image compression
Best in class WordPress image progressive lazy loading
The image lazy loading is the concept of displaying only images when it’s visible to a user (on page scroll). WP Speed of Light lazy loading is the most advanced you can find on WordPress with a smart system that generates a small thumb of few Kb (almost nothing) then load it progressively with a nice effect, keeping your customer on your pages. Furthermore, as we preload 2x screen height, fast connection won’t even notice it! WP Speed of Light lazy loading main advantages:
- Super light lazy loading script
- Progressive image generation and loading effect
- Works on both scroll direction: up to down / down to up
- Almost invisible on fast connections
- Build pages with more content and keep them light!
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.
A plugin dashboard to check all the WordPress performance
The WordPress speed optimization plugin includes a dashboard that checks all major performance issues you have and fix them in one click, pretty handy to optimize performance in no time.
