Drupal Caching

Below is a list of Drupal caching recommendations:

Minimum cache lifetime - Verify that Drupal's minimum cache lifetime is set to never expire.

Minimum cache lifetime is set to 5 min.

Go to /admin/config/development/performance and set "Minimum cache lifetime" to none.

Lock API - Determine the default locking mechanism.

Using the default semaphore database table.

Consider using a dedicated API to a caching backend, such as redis or memcache.

Caching backends - Detail caching backends.

Using the database as a caching backend, which is less efficient than a dedicated key-value store.

Consider using a caching backend such as redis or memcache.
