LiteSpeed Cache (LSCache) is a built-in, high-performance dynamic content acceleration feature of LiteSpeed server products.
LSCache accelerates dynamic content (not just PHP pages), with features very similar to those in Apache mod_cache, using an efficient, highly customizable, native implementation within the LiteSpeed server, which greatly reduces page load time and server load.
LSCache eliminates the extra reverse-proxy layer(s) required by add-on cache packages (such as Varnish), providing faster, more efficient handling of static content in addition to its stellar handling of dynamic content.
Why Use a Plugin?
The LiteSpeed Cache Engine can be controlled through rewrite rules in the .htaccess of a web app's document root. So what do you gain by using an LSCache plugin?
An LSCache plugin bridges the knowledge gap between a web app and the Cache Engine.
Put another way: web apps have rules about what content may be cached, for how long it may be cached, and what events would cause a cache object to become stale. LSCache plugins are a way of communicating these web app rules to the Cache Engine. LSCache plugins allow you to manage the cache in such a way that more objects may be stored for a longer period, and with unparalleled accuracy.
Available Plugins
LSCache plugins are available for many popular CMS:
Magento
WordPress with WooCommerce support
Joomla! with VirtueMart support
XenForo
PrestaShop
MediaWiki
Drupal
Craft CMS
OpenCart
Laravel
No Plugin
If there is no plugin for your CMS, you can still control LSCache with rewrite rules.
LSCache For WordPress Benchmark
We tested HTTP/2 implementations from LiteSpeed Web Server, nginx, and Apache, to see how they would compare when loading WordPress. LiteSpeed beat nginx by up to 12X, and blew Apache out of the water by a whopping 84X! The best available WordPress cache plugins were used for each server: LSCache for LiteSpeed, FastCGI Cache for nginx, and W3 Total Cache for Apache.
Drupal 9 Gets 8X Boost from LiteSpeed Cache!
Drupal 9 sites perform more than 8X faster with LiteSpeed Web Server + LSCache than with nginx + Fast CGI.
LiteMage Makes Magento 2 up to 4 Times Faster!
We took LiteSpeed Web Server, nginx, and Apache, paired them with caching solutions, and tested how their HTTP/2 implementations compared when loading a Magento 2 shop with sample data. LiteSpeed Web Server with LiteMage Cache was up to 3 times faster than nginx with Varnish, and 4 times faster than Apache with Varnish.
