WORDPRESS GLOBAL SPEED OPTIMIZATION DETAILS

 

Powerful WordPress and Browser Caching


Static cache for WordPress

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 & Compare Plugin


Speed test in WordPress admin

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


WordPress database query analysis

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


All CDN WordPress plugin integration: Amazon, KeyCDN, Cloudflare and more

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 cleanup for:

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

 

WordPress Image Compression


Image compression and lazy loading for WordPress

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!

 

Best in Class WordPress Image Lazy Loading


image-lazy-loading

The image lazy loading loads only images when it’s visible by 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 speed 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
  • You'll have the opportunity of building pages with more content and keep them light!

 

Cache Preloading & DNS Prefetching


WordPress Content preloading and domain 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.

 

A Dashboard to Rule All the Performance


Dashboard for Wordpress Performance check

The WordPress Speed 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.

  • 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


WordPress cache per mobile device

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


Custom file exclusion from minification and file group

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.
