LiteSpeed Cache vs WP Rocket: Which Caching Plugin Delivers Better Speed?
Caching is the single most effective tool for accelerating WordPress delivery, but server-level and PHP-level plugins operate on different architectural layers.
1. Architectural Differences
WP Rocket operates at the PHP application layer. When a request arrives, PHP must still initialize before WP Rocket serves the static HTML cache.
LiteSpeed Cache (LSCache) operates directly at the web server layer. Requests are served straight from server memory before PHP ever boots, reducing server CPU overhead to near zero.
2. Cost Comparison
LiteSpeed Cache is completely free when hosted on LiteSpeed servers, whereas WP Rocket requires ongoing annual commercial licenses.
