Why Is My Web App Slow? The Truth About Badly Made React and Next.js

## The Epidemic of "Fat" Applications
React and Next.js are the engines of the biggest Big Techs. But in the wrong hands, they generate gigantic bundles that fry mobile CPUs. Your user abandons your platform if it takes more than **3.2 seconds** to interact.

### 3 Fatal Errors That Destroy Your Performance (And Your SEO):

#### 1. Excessive Client-Side Rendering (CSR)
Sending the user's browser to calculate everything empty and then fill in the data is suicide for SEO and absurd slowness. If you don't use SSR (Server-Side Rendering) or SSG (Static Site Generation), you are in the stone age.

#### 2. Waterfall Requests
Your front-end calls the API. The API calls the Database. The Database queries another table. Returns everything. This \`Waterfall\` destroys the LCP (Largest Contentful Paint).

#### 3. Unmanaged Images and Lack of Edge
Serving original 5MB \`.png\` images from S3 directly into HTML? Without WebP conversion, without smart CDN?

### The Awwwards Performance Approach
RET builds platforms with green metrics (Pass 100) in Lighthouse on Day Zero:
- **Streaming and Suspense**: We show parts of the screen almost instantly before the data is ready.
- **Global Edge**: Your code runs physical milliseconds away from the client.
