TS 7 Native Beats Bun Check on Windows: 0.19s vs 0.27s Type Check Benchmark

mohamedmansour · x · 2026-10-07

Developer mohamedmansour benchmarked TypeScript 7 (the native Go-based compiler) against Bun Check on Windows: on one of his apps, TypeScript 7 finished in 0.19 seconds while Bun Check took 0.27 seconds — the native compiler came out faster.

He also shared a practical tip: invoke the platform binary directly (nodemodules\@typescript\typescript-win32-x64\lib\tsc.exe) instead of going through a wrapper script to avoid overhead.
