The LiteSpeed Cache for WordPress (LSCWP) plugin helps improve WordPress site performance by taking advantage of the LiteSpeed web server’s built-in page cache. The page cache stores content from dynamically-generated pages, resulting in faster page load times for visitors.

Installing LSCWP is easy, and its default settings are appropriate for most web sites. However, the plugin provides a comprehensive user interface that enables you to customize a wide range of settings if you want.
