Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Pigz: Parallel gzip for modern multi-processor, multi-core machines
You can grab the version from the solaris userland repo I linked and use it without me completing a homework assignment. Just grab the pigz-2.3.4 source then apply the patches from [1] in the proper order. Maybe some of them aren't needed for non-Solaris.
1. https://github.com/oracle/solaris-userland/tree/master/compo...
I thought I had opened a PR for that a long while ago, but it doesn't show up on github these days. In any case, I did ask Mark Adler to review it. It was never a priority, then the code changed in ways that I don't really want to deal with.
While looking through the PRs, I noticed a PR for Blocked GZip Format (BGZF) [2]. That's very interesting, and perhaps suggests that bgzip is a tool you would be interested in.

- ZSTD 1.5.5 is released with a corruption fix found at Google
- pigz: A parallel implementation of gzip for multi-core machines

Pigz: A parallel implementation of gzip for multi-core machines
The bit I found most interesting was actually:
https://github.com/madler/pigz/blob/master/try.h
https://github.com/madler/pigz/blob/master/try.c
which implements try/catch for C99.

Is there stronger zip compression than 7z a -mx9?
pigz seems to be able to do it. https://github.com/madler/pigz

Pigz: Parallel gzip for modern multi-processor, multi-core machines
Interesting. It looks like https://github.com/zrajna/zindex became public about a year after my searches for parallel uncompression came up empty and I started hacking on pigz.
What are some alternatives?
rapidgzip - Gzip Decompression and Random Access for Modern Multi-Core Machines
TurboBench - Compression Benchmark
zstd
isa-l - Intelligent Storage Acceleration Library
mpifileutils - File utilities designed for scalability and performance.
containerd - An open and reliable container runtime
solaris-userland - Open Source software in Solaris using gmake based build system to drive building various software components.
zstd - Zstandard - Fast real-time compression algorithm
nvcomp - Repository for nvCOMP docs and examples. nvCOMP is a library for fast lossless compression/decompression on the GPU that can be downloaded from https://developer.nvidia.com/nvcomp.
