How do React, Vue, and Angular compare in real-world performance—initial paint, runtime, and memory usage?

Examines real benchmark data from 2025, focusing on First Contentful Paint (FCP), Speed Index, bundle size, runtime performance, and memory utilization.

A recent benchmark reveals ([turn0search0]): • React: FCP ~0.8 s, Speed Index ~0.8 s, bundle size ~44.5 KB gzipped. Excellent runtime performance with near-zero total blocking time and solid memory efficiency. • Vue: FCP ~1.2 s, Speed Index ~1.7 s, smallest bundle (~34.7 KB). Leads in memory efficiency and rendering performance due to its optimized reactivity system. • Angular: FCP ~1.1 s, Speed Index ~1.2 s, bundle size ~62.3 KB. Runtime performance improved through AOT compilation and incremental hydration, though memory usage is higher than the others. Total blocking time around 200 ms.
