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.

Intel QuickAssist Technology Zstandard Plugin for Zstandard
It's obsolete. It's limited to 32KB LZ window with huffman coding. Zstd can use a much larger window (8MB recommended) and a much better entropy coder: https://github.com/Cyan4973/FiniteStateEntropy

> The modern data compression is mainly based on two approaches to entropy coding: Huffman (HC) and arithmetic/range coding (AC). The former is much faster, but approximates probabilities with powers of 2, usually leading to relatively low compression rates. The latter uses nearly exact probabilities - easily approaching theoretical compression rate limit (Shannon entropy), but at cost of much larger computational cost.

Why is Zip preferred on Mac while RAR seems like the favorite on Windows?
I'm not entirely correct, though. Because Unarchiver likely uses this compression algorithm by calling directly into the API. And there is an open-source implementation for it: lzfse/lzfse.
What are some alternatives?
Snappy - A fast compressor/decompressor
zstd - Zstandard - Fast real-time compression algorithm
LZ4 - Extremely Fast Compression algorithm
zlib-ng - zlib replacement with optimizations for "next generation" systems.
ZLib - A massively spiffy yet delicately unobtrusive compression library.
brotli - Brotli compression format
LZMA - (Unofficial) Git mirror of LZMA SDK releases
PhysicsFS - PhysFS++ is a C++ wrapper for the PhysicsFS library.
smaz - Small strings compression library
