history
Project history and usage
cmix is Byron Knoll's lossless data compression program aimed at compression ratio rather than speed or memory thrift.
Project history
The official homepage describes cmix as a lossless compressor that optimizes compression ratio at the cost of high CPU and memory use, with state-of-the-art results on several compression benchmarks.
The homepage download table records a long public release line beginning with v1 in April 2014 and continuing through v21 in September 2024. The GitHub repository was created in November 2015 and tracks the source-control era of the project.
Adoption history
cmix is distributed narrowly compared with mainstream compressors: the input package facts list Homebrew only. Its adoption is therefore less about day-to-day compression and more about access for people studying or benchmarking high-ratio compressors.
How it is used
The official homepage emphasizes Linux, Windows, and Mac OS X support and recommends at least 32 GB of RAM. That framing makes cmix a benchmark and experimentation tool rather than a default archive format for ordinary users.
Why package nerds care
cmix matters to package nerds because it is a deliberately impractical compressor in the useful sense: high CPU and memory needs make the packaging problem about reproducible builds, large-resource tests, and benchmark comparability rather than command convenience.
