# Baking and code generation

### Baking Video Tutorial

### Overview

Out of the box, **coherence** will use *C# Reflection* to sync all the data at runtime. This is a great way to get started but it is very costly performance-wise.

For optimal runtime performance, we need to **create a schema** and perform **code generation** specific to our project.&#x20;

**coherence** offers an automatic way of doing that called **baking.**

Learn more about this in the [How does coherence work](/0.4.14/overview/how-does-coherence-work.md) section.

### Bake schemas

Click on `coherence -> Bake Schemas`.

This will go through all `CoherenceSync` components in the project and generate a schema file based on the selected variables, commands and other settings. It will also take into account any `CoherenceArchetype` components.

For every prefab with a `CoherenceSync` object, the baking process will generate a bespoke C# file in the `coherence/baked` folder in the project.&#x20;

Adding that file to the prefab will make that prefab use bespoke generated code instead of C# reflection.

### Activate baked schema on prefab

Once the Schema has been baked, you will be able to activate the baked script in the *Configuration* section of the CoherenceSync component.

The name of the baked script will be `CoherenceSync[prefabName]`.
