Overview

WordPress sites often make repeat database queries to retrieve data. Object Cache Pro provides a Redis-backed caching layer for WordPress, storing data so it can be retrieved from the cache rather than requested again from the database. This can help reduce database load and support more responsive site operations.

The plugin supports the WordPress Object Cache API and includes features for cache prefetching, batch requests, and asynchronous flushing. Site owners and developers can inspect cache status with dashboard health information and WP CLI commands, and use opt-in error reporting to help diagnose caching issues. It also supports WooCommerce sites and WordPress multisite networks.

Features

  • Redis object caching: Uses Redis as a WordPress object cache backend, storing and retrieving data through the WordPress Object Cache API.
  • Cache prefetching: Prefetches cached data and combines Redis commands into batches, helping reduce repeated requests to the cache server.
  • WooCommerce compatibility: Supports WooCommerce cache handling for sites with dynamic e-commerce content.
  • Debugging and logging: Offers opt-in error reporting and support for PSR-3 loggers to help developers investigate caching issues.
  • TLS and health checks: Supports encrypted TLS connections and provides cache health information through the WordPress dashboard and WP CLI.
  • Compression options: Supports LZF, LZ4, and Zstandard compression algorithms to reduce Redis memory use and network input and output.
  • Multisite support: Works with WordPress multisite networks and can be deployed as a must-use plugin.

Best for

  • WordPress blogs with repeat database queries
  • WooCommerce stores with dynamic content
  • WordPress multisite network administrators
