Redis Object Cache Management

Full control over Redis object caching, directly from your dashboard.

Cache controls

A new Cache sub-tab in the Performance section lets you toggle caching layers per site.

• Redis Object Cache - enable, disable, or clear the Redis-backed WordPress object cache
• PHP OPcache - toggle PHP bytecode caching on or off, with one-click clear

When Redis is enabled, caching is automatically configured for your WordPress site. Each site gets its own cache namespace so cached data stays fully isolated.

Redis performance metrics

A new Redis card in the Metrics sub-tab tracks four metrics over time:

• Hit rate - percentage of cache lookups served from Redis vs. falling through to the database
• Site keys - number of cached keys belonging to your site
• Memory used - total Redis memory consumption
• Evicted keys - keys removed by Redis under memory pressure (shown only when non-zero)

The hit rate chart shows cache effectiveness at a glance. A healthy site should see 90%+ hit rates after a few minutes of traffic.

How it works

When enabled, frequently used database queries are stored in Redis. On the next request for the same data, WordPress reads from the cache instead of querying the database again - reducing load and speeding up page generation. Each site’s cache is fully isolated.
