3. [LZ4] v1.9.3 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio.
- Levels: 1..12
4. [LZ5] v1.5 is a modification of LZ4 which gives a better ratio at cost of slower compression and decompression.
4. [LZ5] v1.5 is a modification of LZ4 which was meant for a better ratio at cost of slower compression and decompression. It's superseded by [Lizard] now.
- Levels: 1..15
5. [Lizard] v1.0 is an efficient compressor with very fast decompression. It achieves compression ratio that is comparable to zip/zlib and zstd/brotli (at low and medium compression levels) at decompression speed of 1000 MB/s and faster.

- Levels 10..19 (fastLZ4) are designed to give about 10% better decompression speed than LZ4
- Levels 20..29 (LIZv1) are designed to give better ratio than LZ4 keeping 75% decompression speed
- Levels 30..39 (fastLZ4 + Huffman) adds Huffman coding to fastLZ4
