2024 Web Performance Benchmarks

Last updated: December 24, 2025 at 08:46 AM UTC

Note: This page uses Incremental Static Regeneration (ISR) with hourly revalidation. The benchmarks and metrics are refreshed automatically to ensure you always see current data.

Why ISR for This Content?

Performance benchmarks change as:

Frameworks release updates with performance improvements
Browser engines evolve affecting runtime performance
Best practices change based on new research
Package sizes fluctuate with each version

ISR is perfect here because:

✅ Content is mostly static (benchmark methodology doesn't change)
✅ Data needs periodic updates (hourly revalidation)
✅ Users get instant page loads (served from cache)
✅ Fresh data without manual rebuilds

Framework Bundle Size Comparison

One of the most critical metrics for web performance is the initial JavaScript bundle size. Here's a comparison of popular frameworks:

interface BenchmarkData {
  framework: string;
  minified: string;
  gzipped: string;
  firstLoadJS: string;
}
 
const frameworks: BenchmarkData[] = [
  {
    framework: "React 18.2",
    minified: "44.5 KB",
    gzipped: "14.2 KB",
    firstLoadJS: "87 KB"
  },
  {
    framework: "Vue 3.4",
    minified: "34.1 KB",
    gzipped: "11.3 KB",
    firstLoadJS: "72 KB"
  },
  {
    framework: "Svelte 4.0",
    minified: "1.6 KB",
    gzipped: "0.6 KB",
    firstLoadJS: "15 KB"
  },
  {
    framework: "Solid 1.8",
    minified: "7.4 KB",
    gzipped: "2.9 KB",
    firstLoadJS: "23 KB"
  },
  {
    framework: "Next.js 14",
    minified: "99.9 KB",
    gzipped: "32.1 KB",
    firstLoadJS: "102 KB"
  }
];

Key Insights

Smallest Bundles:

Svelte leads with minimal runtime overhead
Solid provides reactivity with a tiny footprint
Vue offers a good balance of features and size

Framework + Routing:

Next.js includes routing, SSR, and optimizations
Bundle size trade-off for powerful features
Consider what you get for the extra bytes

Build Time Performance

Build time matters for developer experience and CI/CD pipelines.

interface BuildMetrics {
  tool: string;
  coldBuild: number;  // ms
  hotReload: number;  // ms
  production: number; // seconds
}
 
const buildTools: BuildMetrics[] = [
  {
    tool: "Vite",
    coldBuild: 392,
    hotReload: 47,
    production: 12.3
  },
  {
    tool: "Webpack 5",
    coldBuild: 3240,
    hotReload: 156,
    production: 45.7
  },
  {
    tool: "Turbopack",
    coldBuild: 201,
    hotReload: 18,
    production: 8.1
  },
  {
    tool: "esbuild",
    coldBuild: 87,
    hotReload: 12,
    production: 2.4
  }
];

Build Performance Winners

esbuild - Blazing fast, written in Go
Turbopack - Rust-based, incremental compilation
Vite - Native ESM, minimal bundling in dev
Webpack - Battle-tested, slower but highly configurable

Memory Consumption

Testing with Chrome DevTools on a complex TodoMVC app:

// Memory benchmarks (MB)
const memoryUsage = {
  "Vanilla JS": 3.2,
  "Svelte": 4.1,
  "Solid": 4.8,
  "Vue": 6.3,
  "React": 8.7,
  "Angular": 11.2
};
 
// Reactivity update performance (ops/sec)
const reactivityBench = {
  "Solid": 12500,
  "Vue": 8900,
  "Svelte": 8200,
  "React": 3400
};

Real-World Bundle Analysis

Let's analyze a typical e-commerce product page:

interface PageMetrics {
  component: string;
  size: string;
  impact: "High" | "Medium" | "Low";
}
 
const productPageBreakdown: PageMetrics[] = [
  { component: "Framework Runtime", size: "44 KB", impact: "High" },
  { component: "UI Component Library", size: "67 KB", impact: "High" },
  { component: "Form Validation", size: "12 KB", impact: "Medium" },
  { component: "Image Carousel", size: "23 KB", impact: "Medium" },
  { component: "Analytics", size: "18 KB", impact: "Low" },
  { component: "Chat Widget", size: "45 KB", impact: "Low" },
];
 
// Total: 209 KB (before compression)
// Gzipped: ~68 KB

Optimization Strategies

1. Code Splitting

// Bad: Everything loaded upfront
import { HeavyComponent } from './HeavyComponent';
 
// Good: Load on demand
const HeavyComponent = lazy(() => import('./HeavyComponent'));
 
// Even better: Load when visible
const HeavyComponent = lazy(() =>
  import('./HeavyComponent').then(module => ({
    default: module.HeavyComponent
  }))
);

2. Tree Shaking

// Bad: Imports entire library
import _ from 'lodash';
const result = _.debounce(fn, 300);
 
// Good: Import only what you need
import debounce from 'lodash/debounce';
const result = debounce(fn, 300);
 
// Better: Use modern alternatives
const debounce = (fn, ms) => {
  let timeout;
  return (...args) => {
    clearTimeout(timeout);
    timeout = setTimeout(() => fn(...args), ms);
  };
};

Performance Budget

Recommended budgets for different app types:

App Type	JavaScript	Total Size	FCP	TTI
Blog	50 KB	200 KB	< 1s	< 2s
E-commerce	150 KB	500 KB	< 1.5s	< 3s
Dashboard	250 KB	800 KB	< 2s	< 4s
Social Media	200 KB	700 KB	< 1.5s	< 3.5s

Conclusion

Choose based on your needs:

Maximum Performance: Vanilla JS or Svelte
DX + Performance: Solid or Vue
Ecosystem + Features: React or Next.js
Enterprise Scale: Angular

Remember: The best framework is the one that helps your team ship fast while meeting performance budgets.
