So, lean-zip "outperforming an equivalent Rust package that crates.io says has been downloaded over a billion times". Yes, zlib-rs has only been downloaded 200 million times... But it is way faster!
- The faster package may have been available for a shorter amount of time and so downloads have not had the time to catch up yet.
- Many people may not be aware of the faster package, but they would switch if they knew.
- Maybe people are aware of the faster package, but there are switching costs that prevent them from adopting it right now that are greater than the costs incurred from the slower package.
