Optimize hooks for large datasets

**Feature request**
It would be great to have caching for core.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_caching` with default `false`.

The issue identifies only the core and a new enable_caching configuration option; no file, test, or entry point is named. Start by locating the core configuration handling and existing deployment behavior. Done means caching is implemented for the intended production use case, is controlled by enable_caching, and defaults to false.
