Questions the author answers
Why do the cache features require LiteSpeed Server?
This plugin communicates with your LiteSpeed Web Server and its built-in page cache (LSCache) to deliver superior performance to your WordPress site. The plugin’s cache features indicate to the server that a page is cacheable and for how long, or they invalidate particular cached pages using tags.
LSCache is a server-level cache, so it’s faster than PHP-level caches. Compare with other PHP-based caches.
What about the optimization features of LSCache?
LSCWP includes additional optimization features, such as Database Optimization, Minification and Combination of CSS and JS files, HTTP/2 Push, CDN Support, Browser Cache, Object Cache, Lazy Load for Images, and Image Optimization! These features do not require the use of a LiteSpeed web server.
Is the LiteSpeed Cache Plugin for WordPress free?
Yes, LSCWP will always be free and open source. That said, a LiteSpeed server is required for the cache features, and there are fees associated with some LiteSpeed server editions. Some of the premium online services provided through QUIC.cloud (CDN Service, Image Optimization, Critical CSS, Low-Quality Image Placeholder, etc.) require payment at certain usage levels.
What server software is required for this plugin?
A LiteSpeed solution is required in order to use the LiteSpeed Exclusive features of this plugin. Any one of the following will work:
- LiteSpeed Web Server Enterprise with LSCache Module (v5.0.10+)
- OpenLiteSpeed (v1.4.17+)
- LiteSpeed WebADC (v2.0+)
- QUIC.cloud CDN
The General Features may be used with any web server. LiteSpeed is not required.
Does this plugin work in a clustered environment?
The cache entries are stored at the LiteSpeed server level. The simplest solution is to use LiteSpeed WebADC, as the cache entries will be stored at that level.
If using another load balancer, the cache entries will only be stored at the backend nodes, not at the load balancer.
The purges will also not be synchronized across the nodes, so this is not recommended.
Where are the cached files stored?
The actual cached pages are stored and managed by LiteSpeed Servers.
Nothing is stored within the WordPress file structure.

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
