Slow Initial Page Load and Time to Interactive

App takes 5+ seconds to load initial page. Blank white screen for extended period. Users see slow Time to First Contentful Paint (FCP) and Time to Interactive (TTI). Performance metrics are poor.

Page load speed depends on bundle size, network latency, and resource blocking. Optimizations include code splitting, lazy loading, and resource prioritization.

Common Causes

  1. Large JavaScript bundle (>500KB) not split
  2. Loading all npm packages upfront instead of lazy loading
  3. Large images or unoptimized assets
  4. Synchronous scripts blocking HTML parsing
  5. Missing gzip compression on assets

How to Fix It

Analyze bundle in Vite:

npm run build -- --visualizer

Code split with React.lazy():

const Dashboard = lazy(() => import('./Dashboard'));

Use Lighthouse DevTools to identify bottlenecks.

Frequently Asked Questions

What's a good FCP time?

Under 1.8 seconds is good. Measure with Lighthouse. Aim for <3 seconds for Time to Interactive.

How do I reduce bundle size?

Use dynamic imports for routes, lazy load heavy libraries, remove unused dependencies, use tree-shaking.
