Lizard v1.0 is an efficient compressor with fast decompression. LZ5 v1.5 is a modification of LZ4 which was meant for a better ratio at cost of slower compression and decompression. A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). LZ4 v1.9.4 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It is similar in speed with deflate but offers more dense compression. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder.īrotli v.1.0.9 is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. Zstandard v1.5.5 is a real-time compression algorithm, providing high compression ratios.
