Great article, summarizing the key points here:

1. Parallel API requests using Promises.all()

2. Lazy loading components only when needed

3. Preload data in advance for user interactions to enhance responsiveness

4. Generating static HTML at build time (static site generation), for faster initial load.

5. Using React server components, for offloading heavy computations and stream HTML to the client, reducing the client’s load, improving user interaction time.
