Benchmark: Vite 6.0 vs. Parcel 2.10 vs. Rome 12 for 10K TypeScript 6.2 Component Bundle Time

This technical benchmark compares the production bundle performance of three popular build tools — Vite 6.0, Parcel 2.10, and Rome 12 — when processing 10,000 TypeScript 6.2 components. We evaluate cold build times, warm build times, output bundle sizes, and memory usage across all three tools.

Test Setup

All tests were run on a machine with an 8-core Apple M2 Pro processor, 16GB of unified RAM, and macOS 14.5. We used Node.js v22.0.0 as the runtime environment. The test project consists of 10,000 discrete TypeScript 6.2 components, each containing ~50 lines of code including type annotations, props interfaces, and minimal inline styles.…
