| Name: zstd | Distribution: SUSE Linux Enterprise 15 |
| Version: 1.5.0 | Vendor: SUSE LLC <https://www.suse.com/> |
| Release: 150400.3.3.1 | Build date: Tue Mar 21 15:43:22 2023 |
| Group: Productivity/Archiving/Compression | Build host: ibs-arm-4 |
| Size: 2129704 | Source RPM: zstd-1.5.0-150400.3.3.1.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.

libs.
* Fri Jun 14 2019 idonmez@suse.com
- Remove googletest-devel BuildRequires and pzstd-global-gtest.patch
because we want zstd in ring0 (due to rpm's zstd payload support)
Since googletest is only used in build time (it's for testing after
all), this should be fine.
