Benchmarks

Methodology

All benchmarks run on dockerized S3 backends — MinIO, Garage, SeaweedFS, and RustFS — using mixed file sizes. Each tool is tested with default settings unless otherwise noted.

Tools compared:

Tool	Language	Notes
s3z	Rust	This library
`s5cmd`	Go	Popular parallel S3 client
`mc`	Go	MinIO client
`aws-cli`	Python	Official AWS CLI

These benchmarks measure tool throughput in isolation on local dockerized backends. They do not represent production AWS S3 latency or real-world network conditions.
