Bun parses 1 billion‑row 13.8 GB file in under 10 seconds
A developer tackled the 1 Billion Row Challenge using Bun/TypeScript, parsing a 13.8 GB temperature file in under 10 seconds. By opening the file with low‑level descriptors and zero‑copy chunk reads, he avoided Bun’s 4 GB buffer cap. The result proves Bun can handle massive streaming workloads far faster than typical Node.js approaches.
