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:
- Static file cache system
- Gzip data compression
- Browser caching
- Files group: CSS, JS, Local fonts, Google Fonts
- Resources minification: HTML, CSS, JS
- Specific mobile cache per device
- Remove query string
- Cache external scripts
- Option to disable WordPress features like REST API, RSS feeds, Gravatar, Emojis
- Automatic cache clean: by interval, on save, by user group
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
