Overview
QuantumCache speeds up WordPress by caching database query results (not full pages). It integrates with WordPress query execution to cache post ID lists and content fragments that WordPress uses to build pages, reducing database load while preserving correct invalidation.
It is not an output buffer or page cache, and it does not replace existing page caching solutions.
Features
- Caches the results of the main front-end
WP_Queryfor anonymous requests. - Tag-based invalidation: purge by post ID, post type, or taxonomy.
- Fragment caching for

- Auto – use Redis if available, otherwise fall back to MySQL.
- Redis – fastest mode; uses the PHP Redis extension…
