Instructions for installing and using the LiteSpeed Cache plugin for WordPress


Notes when installing and using the LiteSpeed Cache plugin.

First of all, when installing the LiteSpeed Cache plugin, you need to check whether the VPS or hosting you are installing has OpenLiteSpeed Web Server or uses LiteSpeed Web Server. It can be said that litespeed cache will work best on these two web servers. LiteSpeed Cache can work on other web servers such as Apache, NGINX… But to take advantage of all the features of the LiteSpeed Cache plugin you need OpenLiteSpeed, LiteSpeed or the CDN service. See more about installing OpenLiteSpeed.

But in our real test cases. For websites that have used the LiteSpeed Cache plugin, it is cache software. Web servers using OpenLiteSpeed and LiteSpeed Web Server will provide much faster speeds. Websites that use the LiteSpeed Cache plugin with a web server using OpenLiteSpeed or LiteSpeed Web Server also help the website become more stable. Websites that combine the above two software can both reduce web server load and speed up and optimize the website very well.

It’s no wonder the LiteSpeed Cache plugin has more than 4 million plugin installs on WordPress. When installing, many people complain about the LiteSpeed Cache plugin, but most of them do not combine it with a dedicated web server for the LiteSpeed Cache plugin, so the performance is often not high compared to other cache plugins.
