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 also seems to suggest that it could accelerate hyperscan, but considering the hardware and software are both from Intel and they don't integrate them, maybe it doesn't work or is theoretical.

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

Silly Lossy Text Compression Idea
Sounds similar to: https://github.com/Cyan4973/FiniteStateEntropy
https://arxiv.org/abs/1311.2540
> 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.
