Since its earliest versions, Nippy has consistently been the **fastest serialization library for Clojure** that I'm aware of. It offers:

- Roundtrip times **>12x faster** than `tools.reader` with **60% smaller** data size.
- Roundtrip times **>2x faster** than `data.fressian` with **30% smaller** data size.
- **0.3x** the roundtrip time and **0.6x** the output size of `tools.reader`
- **0.7x** the roundtrip time and **0.7x** the output size of `data.fressian`
