This allows you to optimize various elements in themes and plugins to use caching to save resources and reduce response times. You can also use caching methods like Memcached or Redis (for example) to scale. Instructions for use are available in the FAQ available under the help menu. This feature also gives you control over the caching policies by the group as well as visibility into the configuration by extending the WordPress Object API with additional functionality.', 'w3-total-cache' ),
