## Minimize Serialization at RSC Boundaries
The React Server/Client boundary serializes all object properties into strings and embeds them in the HTML response and subsequent RSC requests. This serialized data directly impacts page weight and load time, so **size matters a lot**. Only pass fields that the client actually uses.
**Incorrect (serializes all 50 fields):**
```tsx
async function Page() {
const user = await fetchUser(); // 50 fields
return <Profile user={user} />;
}
("use client");
function Profile({ user }: { user: User }) {
return <div>{user.name}</div>; // uses 1 field
}
```
**Correct (serializes only 1 field):**
```tsx
async function Page() {
const user = await fetchUser();
return <Profile name={user.name} />;
}
("use client");
function Profile({ name }: { name: string }) {
return <div>{name}</div>;
}
```
