86 which can be loaded before compression and decompression.
88 Using a dictionary, the compression ratio achievable on small data improves dramatically.
89 These compression gains are achieved while simultaneously providing faster compression and decompre…
92 Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm
103 CLI includes in-memory compression benchmark module for zstd.
109 The benchmark measures ratio, compressed size, compression and decompression speed.
110 One can select compression levels starting from `-b` and ending with `-e`.
123  -#     : # compression level (1-19, default: 3)
128 --rm    : remove source file(s) after successful de/compression
140 --no-dictID : don't write dictID into header (dictionary compression)
160  -b#    : benchmark file(s), using # compression level (default: 3)
161  -e#    : test all compression levels from -bX to # (default: 1)
170 the compression ratio for files with long matches at a large distance (up to the
171 maximum window size, `128 MiB`) while still maintaining compression speed.
179 Below are graphs comparing the compression speed, compression ratio, and
199 On this file, the compression ratio improves significantly with minimal impact
200 on compression speed, and the decompression speed doubles.
203 the [Silesia compression corpus]) will likely lead to a deterioration in
204 compression speed (for lower levels) with minimal change in compression ratio.
206 The below table illustrates this on the [Silesia compression corpus].
