Back your WP Object Cache with Redis, a high-performance in-memory storage backend.
If you are concerned with the speed of your site, backing it with a high-performance, persistent object cache can have a huge impact. It takes load off your database, and is faster for loading all the data objects WordPress needs to run.
This plugin is for the internal application object cache. It doesn't have anything to do with page caches. On Pantheon you do not need additional page caching, but if you are self-hosted you can use your favorite page cache plugins in conjunction with WP Redis.
A page load with 2,000 Redis calls can be 2 full seonds of object cache transactions. If a plugin you're using is erroneously creating a huge number of cache keys, you might be able to mitigate the problem by disabling cache persistency for the plugin's group:
wp_cache_add_non_persistent_groups( array( 'bad-actor' ) );
This declaration means use of
wp_cache_set( 'foo', 'bar', 'bad-actor' ); and
wp_cache_get( 'foo', 'bad-actor' ); will not use Redis, and instead fall back to WordPress' default runtime object cache.
