LiteSpeed Cache for Drupal 8
Drupal 8 is significantly changed from Drupal 7. They have converted from procedural programming to object-oriented programming. Drupal 8 has a built-in page cache (for static content) and a dynamic page cache for logged in users. The latter basically works as a reverse proxy written in PHP. The built-in proxy is good if you have no other options, however, with the LiteSpeed Cache plugin you will see a great improvement in performance for your Drupal 8 site.

This version of LiteSpeed Cache requires Drupal 8.xx or later and LiteSpeed Web Server (LSWS) 5.2.3 or later.
