Improve hooks performance

**Feature request**
It would be great to have serialization for data.

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

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

The issue names no files, tests, or entry points beyond hooks and the proposed enable_serialization option. Start by locating the hooks implementation and configuration handling, then determine what data must be serialized and how production deployments should verify it; done means the option defaults to false and the requested serialization behavior is covered by tests.
