By default, all events are sent to Speed Insights.
To send only a sample of your data, you can add the Speed Insights component with the [`sampleRate`](/docs/speed-insights/package#samplerate) prop to your app's root layout. The [`sampleRate`](/docs/speed-insights/package#samplerate) prop accepts a number between 0 and 1, where 0 is 0% and 1 is 100%:
```ts
import { SpeedInsights } from '@vercel/speed-insights/next';
export default function RootLayout({ children, }: {children: React.ReactNode;}) {
return (
Next.js
{children}
);
}
```
