When building SaaS dashboards, performance is a feature. Users expect their data to load instantly, even when query results are massive. Modern frameworks allow us to shift the heavy lifting to the server side.

export default async function DashboardChart() {
  const data = await fetchAnalyticsData();
  return <ChartRenderer data={data} />;
}

Streaming and Suspense

By using React Suspense, you can stream parts of the page as they become ready. This means a user can see their 'User Count' card immediately while a more complex 'Revenue Growth' chart is still being calculated in the background.
