Zstandard - Fast real-time compression algorithm
Zstd, short for Zstandard, is a real-time compression algorithm providing high compression ratios. It offers a very wide range of compression vs. speed trade-offs while being backed by a very fast decoder. It offers a special mode for small data called “dictionary compression” and it can create dictionaries from any sample set. Zstd is BSD-licensed.
Using Izbench on the Silesia compression corpus, zstd ranked at the top with a compression ratio of 2.877, a compression rate of 325 Mb/s, and a decompression rate of 325. Zlib followed at 2.730, 95 Mb/s C and 360 Mb/s D. See WWW page for the full benchmark results.
