In plain words
pzip is a concurrent zip archiver and extractor designed for speed. It allows users to create and extract zip files with parallel processing capabilities. The tool is built for anyone needing to work with compressed archives more efficiently than traditional single-threaded approaches. Its main distinguishing feature is the use of concurrency to accelerate compression and decompression operations.

Thread-Parallel Decompression and Random Access to Gzip Files (Pragzip)2022 · github.com · ▲15Hello HN, I'm very excited to have finished a gzip decoder that can speed up decompression using threads. On my Ryzen 3900X, I measured a 8x speedup over standard gzip, reaching 1.6 GB/s for a synthetic file with a consistent compression ratio of 1.3. A functional decompressor like this is kind of a first, that's why I am excited. Pragzip implements the two-staged decompression idea put forward with pugz, which unfortunately only works with gzipped text files not arbitrary files and has many more limitations. I think my main contribution over pugz might be a fast (~10 MB/s)…
Rapidgzip – Truly Parallel Gzip Decompression with 10 GB/s2023 · github.com · ▲35I have posted a much earlier version of this over a year ago [0]. Since then a lot has changed. Obviously, the name has changed. This happened for the paper publication [1]. I have also optimized the speed, integrated ISA-L for special cases, limited the compression-ratio-dependent maximum memory consumption, and finally added parallelized CRC32 computation, which adds ~5% overhead no matter the number of cores used. At this point, I am leaning towards calling it production-ready although there are still many ideas for improvements. Redoing the benchmarks of the older Show HN, would look…
