I built a faster alternative to cp and rsync — here's how it works
Summary

fast-copy is a Python CLI that accelerates file copies by sorting files via OS-specific APIs (FIEMAP/fcntl/FSCTL) for sequential disk I/O, deduplicating with xxHash-128 and a SQLite cache, and streaming ~100 MB tar batches over SSH to avoid SFTP overhead, reporting 3x speedups in benchmarks.
