In my first post about Content SDK, I illustrated the benefits of native server components. In this post we will get more into the details of why this is so beneficial. Modern Next.js performance is built on React Server Components (RSC), streaming, and intelligent caching. These capabilities were largely out of reach when using Sitecore JSS.

Here are reasons why Sitecore Content SDK changes that.

Server Components by Default

With the Content SDK, content fetching happens naturally inside Server Components:

• Server side GraphQL
• No hydration tax for content rendering
• Smaller JavaScript bundles
• Improved security

Streaming & Suspense

Because rendering is no longer centralized, streaming works out of the box:

<Suspense fallback={<Skeleton />}>

 <Article />

</Suspense>

This allows:

• Faster perceived performance
• Progressive page loading
• Better Core Web Vitals

With JSS, this level of control was effectively impossible.

A More Performant Default

The biggest shift is not a specific feature, it’s the default behavior.

With Content SDK:

• Server rendering is the norm
• Client rendering is opt-in
• Performance comes naturally
