Lines Matching full:compression

3 __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].

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.
67 Speed vs Compression trade-off is configurable by small increments.
69 a property shared by most LZ compression algorithms, such as [zlib] or lzma.
