Speed vs Compression trade-off is configurable by small increments.ĭecompression speed is preserved and remains roughly the same at all settings,Ī property shared by most LZ compression algorithms, such as zlib or lzma. Zstd can also offer stronger compression ratios at the cost of compression speed. Offer faster compression and decompression speedĪt the cost of compression ratio (compared to level 1). The negative compression levels, specified with -fast=#, Using lzbench, an open-source in-memory benchmark by with gcc 9.3.0, On a desktop running Ubuntu 20.04 ( Linux 5.11.0-41-generic), Should your project require another programming language,Ī list of known ports and bindings is provided on Zstandard homepage.įor reference, several fast compression algorithms were tested and compared This repository represents the reference implementation, provided as an open-source dual BSD and GPLv2 licensed C library,Īnd a command line utility producing and decoding. Multiple independent implementations are already available. Zstandard's format is stable and documented in RFC8878. It's backed by a very fast entropy stage, provided by Huff0 and FSE library. Targeting real-time compression scenarios at zlib-level and better compression ratios. Zstandard, or zstd as short version, is a fast lossless compression algorithm,
