Which is faster client-side or server-side?

Between the two options, server-side rendering is better for SEO than client-side rendering . This is because server-side rendering can speed up page load times, which not only improves the user experience, but can help your site rank better in Google search results.

In Client-side rendering, your browser downloads a minimal HTML page. It renders the JavaScript and fills the content into it. Server-side rendering, on the other hand, renders the React components on the server. The output is HTML content. You can combine these two to create an isomorphic app.

A server is generally going to be orders of magnitude more powerful than a client machine ; and managed code is generally much faster than scripting. However – the client machine also usually has a lot of spare computational power that isn’t being used, while the server could be running requests for thousands of users.
