Fast Lossless Compression Algorithm

Github repositories

• lz4/lz4

  LZ4 is an open-source, extremely fast lossless compression algorithm. It achieves compression speeds of over 500 MB/s per core and can scale with multi-core CPUs. The decoder is also remarkably fast, reaching speeds of multiple GB/s per core. Users can dynamically adjust the speed by selecting an "acceleration" factor. LZ4 includes LZ4_HC, a high compression derivative that trades CPU time for improved compression ratio. It supports dictionary compression and can be combined with the Zstandard Dictionary Builder for enhanced performance on small files. The library is provided under the BSD 2-Clause license.
