README.md

File benchmarks in JavaScript

Requirement: We assume that have macOS or Linux. Windows is not supported.

Run the bash script script.sh (e.g., type bash script.sh). It will install nvm and bun in your user account, if needed.

The benchmark simply reads the current README.md file, as quickly as possible.

The README file may contain non-ASCII characters: é, ê, ô.
