H A DREADME.md3 __Zstandard__, or `zstd` as short version, is a fast lossless compression algorithm,
4 targeting real-time compression scenarios at zlib-level and better compression ratios.
34 For reference, several fast compression algorithms were tested and compared
39 on the [Silesia compression corpus].
42 [Silesia compression corpus]: http://sun.aei.polsl.pl/~sdeor/index.php?page=silesia
62 The negative compression levels, specified with `--fast=#`,
63 offer faster compression and decompression speed
64 at the cost of compression ratio (compared to level 1).
66 Zstd can also offer stronger compression ratios at the cost of compression speed.
69 a property shared by most LZ compression algorithms, such as [zlib] or lzma.
