1. Caching

LightSpeed Cache and WP Rocket offer full-page caching. Instead of waiting for PHP to process and fetch data from a database after each request, these plugins can deliver the content much faster. However, the two are slightly different because LightSpeed Cache uses server-level caching. 

Instead of handling the caching, the LiteSpeed web server cache deals with the process. Therefore, the plugin makes it easy for WordPress to communicate with the cache engine. Additionally, the files are not stored in the WordPress file structure. As a result, this server-level caching is faster than WP Rocket’s file-based caching.

Although caching may not directly boost the PageSpeed scores, you’ll notice an improvement.

2. Image Optimization

WP Rocket has add-on features for image optimization and compression. However, if you want to optimize your images, you have to buy plugins like Cloudflare or Imagify, which means you have to spend more on your budget. 

However, LightSpeed Cache has these optimization features, making it ideal for your WordPress site. With this plugin, you can reduce the size of your images to improve the load times. You can also revert the individual images to their original formats. Additionally, LightSpeed Cache makes using the WebP file format easy if you have small image files. 

3. Content Delivery Network (CDN)

Your website content is stored on multiple servers in a content delivery network (CDN). When a user requests information, the CDN confirms the IP address and loads the website from the nearest server.

LightSpeed Cache provides CDN. This CDN includes a QUIC dashboard; therefore, it’s easy to configure the settings, and you can adjust it according to your needs. In addition, users can choose between the free and standard plans. Both plans work like Cloudflare because they use HTML caching.

On the other hand, WP Rocket offers Rocket CDN, which serves files from another partner, StackPath. Unlike, Rocket CDN does not have a dashboard; therefore, users don’t have much room for configuration. In addition, although Rocket CDN offers unlimited bandwidth for $7.99 per month, there are customer reports that it cuts users off when they use too much bandwidth. has an advantage because they offer free monthly credits, and its pricing is regional-based, depending on your chosen region.  

4. File Optimization

These features come in handy if you want to address the Google PageSpeed recommendations or improve Core Web Vitals. As a result, your website will achieve better performance scores, which boosts user experience. 

LiteSpeed Cache has features like Remove Unused Files, CSS optimization, CSS and JavaScript Combination, Crawler, and minification of CSS, JavaScript, and HTML files. These file optimization tools play a role in improving the overall website speed. 

5. Edge Side Includes (ESI)

ESI is defined as a markup language that web developers use to designate parts of the web page as sections to be processed separately. ESI makes it easy to deliver pages more quickly and accurately using caching. In addition, it reduces the distance data travels, the traffic, and the volume of data. Therefore, thanks to ESI, the web page can be broken into different sections and reassembled before the browser delivery. 

WP Rocket does not have ESI, but LightSpeed Cache has this feature. Therefore, if you have an e-commerce page, ESI allows you to cache pages that contain shopping cart data and any other private content. This is one of the reasons why LightsSpeed Cache is ideal for large WooCommerce sites.
