Top 7 C Lz4 Projects

LZ4

10 7,915 9.3 C

Extremely Fast Compression algorithm

Project mention: Micron Unveils 24GB and 48GB DDR5 Memory Modules | AMD EXPO and Intel XMP 3.0 compatible | reddit.com/r/gadgets | 2023-01-21

Yeah, sure, when you have monster core counts. on regular systems, not so much, here's from their own github page. it achieves, eh, 5GB/s on memory to memory transfers, i.e. best case scenario. so, uh, no? i'm not even sure it's any better than the CPU decompressor one Nvidia used.
7-Zip-zstd

17 2,984 5.3 C

7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard

Project mention: Forspoken running on RX480 on Ubuntu , most of the time it's above 30FPS. It's pretty playable so AMD should release a fix for Polaris cards to make it playable on Windows. | reddit.com/r/Amd | 2023-01-27

Reliable PostgreSQL Backup & Restore

Project mention: pgBackRest - have you used it and what was your experience? | reddit.com/r/Database | 2023-01-26
lzbench

1 712 0.0 C

lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors

Project mention: Lizard – efficient compression with fast decompression | news.ycombinator.com | 2022-05-24

Note that a benchmark in the README refers to zstd 1.1.1 and brotli 0.5.2, which are very old (the current versions are zstd 1.5.2 and brotli 1.0.9). The same author maintains lzbench [1], which is more or less up-to-date.

p7zip

7 583 0.0 C

A new p7zip fork with additional codecs and improvements (forked from https://sourceforge.net/projects/sevenzip/ AND https://sourceforge.net/projects/p7zip/).

Project mention: 7-zip 22.00 – APFS, Posix TAR, high precision timestamps | news.ycombinator.com | 2022-06-23

Thank you for pointing this out! This is the source of much confusion. Although Arch for example uses https://github.com/jinfeihan57/p7zip which seems to be reasonably maintained?
lizard

1 581 0.0 C

Lizard (formerly LZ5) 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. (by inikep)
