WP Speed of Light - Speed Up WordPress

The WordPress Speed Optimization, Live

 

 

Powerful 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:

• 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

 

Check WordPress Speed and Compare

---

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

---

A CDN (Content Delivery Network) integration is available. It is compatible with all the major CDN on the market like Cloudflare, Amazon Cloudfront, MaxCDN, KeyCDN and others. Plus, there's a specific automatic cache cleaup for:

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

 

Image Compression and Lazy Loading

---

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 tool and a lazy loading option:

• Image Compression: Apply an invisible image compression and reduce image size by up to 80% (by ImageRecycle)
• Lazy loading: Load only images when it’s visible in the by user (on scroll)
• Exclude URL or a set of URLs from the image lazy loading

 

Cache Preloading and DNS Prefetching

---

The cache pre-loading 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.

 

A Dashboard to Rule All the Performance

---

A dashboard is available to check all major performance issues you have and fix them in one click, pretty handy to optimize performance in no time.

• Check for WordPress cache activation and duration
• Check for WordPress Gzip activation
• Check for resources group and minification
• Expire Headers presence and duration
• Check website loading time (latest test)
• Auto Clear cache activation
• Check the number of plugins in use
• Check for PHP version

 

Selective Cache for Mobile Devices

---

WP Speed of Light can handle the cache for mobile automatically, and you can generate a dedicated cache version per device or even disable it. The plugin also works automatically with mobile plugins like WPtouch. Mobile cache features:

• Automatically serve cache for all devices
• Dedicated cache for tablet
• Dedicated cache for tablet
• Option to disable cache for a specified device

 

Visual File Exclusion from Group & Minification

---

The file group and minification is one the tricky stuff to configure on complex WordPress website with tons of plugins. We've made the process simple in WP Speed of Light: Scan your website and index the files then, if needed, exclude one or several files from the process by using a simple ON/OFF button.
