Wed Apr 17 11:30:30 UTC 2019 - Jan Engelhardt <jengelh@inai.de>
- Update to new upstream release 1.4.0
* perf: level 1 compression speed was improved by ~6–8%
* cli: added --[no-]compress-literals flag to enable or disable
literal compression
- Reword "real-time" in description by some actual statistics,
because 603MB/s (lowest zstd level) is not "real-time" for
quite some applications.

%description
Zstd, short for Zstandard, is a lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.
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.
Zstd can also offer stronger compression ratios at the cost of
compression speed. Speed vs. compression trade-off is configurable by
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 (v1.3.5) achieves ~600%% faster
compression than zlib. At roughly the same time, zstd achives a ~12%%
better ratio than gzip. LZMA outperforms zstd by ~10%% faster
compression for same ratio, or ~9%% size reduction for same time.
