| Name: zstd | Distribution: SUSE Linux Framework One |
| Version: 1.5.5 | Vendor: SUSE LLC <https://www.suse.com/> |
| Release: slfo.1.1.10 | Build date: Thu Apr 13 13:15:39 2023 |
| Group: Productivity/Archiving/Compression | Build host: reproducible |
| Size: 1845724 | Source RPM: zstd-1.5.5-slfo.1.1.10.src.rpm |

| Summary: Zstandard compression tools | |
Zstd, short for Zstandard, is a lossless compression algorithm. Speed vs. compression trade-off is configurable in small increments. Decompression speed is preserved and remains roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma. At roughly the same ratio, zstd (v1.4.0) achieves ~870% faster compression than gzip. For roughly the same time, zstd achives a ~12% better ratio than gzip. LZMA outperforms zstd by ~10% faster compression for same ratio, or ~1–4% size reduction for same time.
