27 the identifier B<id> to the list of available compression methods. This

34 SSL_COMP_get0_name() returns the name of the compression method B<comp>.
36 SSL_COMP_get_id() returns the id of the compression method B<comp>.

43 The TLS standard (or SSLv3) allows the integration of compression methods
44 into the communication. The TLS RFC does however not specify compression
46 way to integrate compression with unknown peers. It is therefore currently not

H A Dzstd.1.md18 `zstd` is a fast lossless compression algorithm and data compression tool,
21 `zstd` offers highly configurable compression speed,
23 to strong modes with excellent compression ratios.
25 which remains roughly stable at all compression settings.
95 Benchmark file(s) using compression level _#_.
109 selects `#` compression level \[1-19\] (default: 3).
110 …Higher compression levels *generally* produce higher compression ratio at the expense of speed and…
111 A rough rule of thumb is that compression speed is expected to be divided by 2 every 2 levels.
115 unlocks high compression levels 20+ (maximum 22), using a lot more memory.
118 switch to ultra-fast compression levels.

H A DREADME.md72 - __ZSTD_NOCOMPRESS__ : `zstd` cli will be compiled without support for compression.
111 which can be loaded before compression and decompression.
113 Using a dictionary, the compression ratio achievable on small data improves dramatically.
114 These compression gains are achieved while simultaneously providing faster compression and decompre…
117 Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm
128 CLI includes in-memory compression benchmark module for zstd.
135 The benchmark measures ratio, compressed size, compression and decompression speed.
136 One can select compression levels starting from `-b` and ending with `-e`.
140 such as number of threads (`-T#`), or advanced parameters (`--zstd=#`), or dictionary compression (…
