There are many more sections to explore in the LSCache plugin. Each of these is documented in much greater detail.


The LiteSpeed Cache Dashboard allows you to see the status of all of your LSCache and services (Image Optimization, Critical CSS Generation, Low-Quality Image Placeholders, Cache Crawler, etc.) at a glance. You can also check your page load time and your page speed score.


The settings in this section control your usage of services, the ability to auto-upgrade the plugin, and which messages you want to have displayed on the dashboard.


This section allows you to configure your Content Delivery Network for use with WordPress. If you don’t use a CDN, don’t worry about it. CDN support is disabled by default.

Image Optimization

LiteSpeed Cache for WordPress provides the ability to optimize your images, making them smaller, and faster to transmit. This is done through a QUIC. Cloud service and can be controlled in this section of the plugin.

Page Optimization

There are several non-cache measures you can take to speed up your WordPress site, and many of them are supported in this tab. CSS and JavaScript minification and combination, HTTP/2 push, asynchronous and deferred load… if you don’t know what these things mean, don’t worry. They are disabled by default.


This section allows you to optimize your WordPress database. Database optimization is a useful tool when it comes to speeding up your site. LSCWP’s DB Optimizer gives you an easy way to execute some of these tasks in your WordPress database.


The crawler is disabled by default. When it’s active, it travels your site, refreshing any pages that may have expired from the cache. Crawling can be a resource-intensive process, and not all hosting providers will allow its use. If your hosting provider does allow crawling, it’s a nice way to keep your cache fresh.


When you need to manually purge the cache, export your site settings, or debug an issue, you’ll find the means in the Toolbox section. Probably the most useful thing you will find here is the Environment Report. If you are having a problem and LiteSpeed support asks for your Report Number,.
