Overview of available caching options in OpenPanel
OpenPanel provides several caching and performance tools:
- Redis/Valkey: Persistent object cache backends storing data in RAM to accelerate database and website queries. Valkey is a drop-in replacement for Redis.
- Memcached: In-memory object cache specifically for reducing database load; recommended for use with PHP OPcache rather than Redis.
- Elasticsearch/OpenSearch: Powerful search and analytics engines for efficient information retrieval and log analytics.
- Varnish: A reverse caching proxy and HTTP accelerator for dynamic websites and APIs.
- OPcache: Caches precompiled PHP script code in shared memory to reduce CPU load. This is enabled by default for PHP.
