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.

The Technical Workloads Where AMD Ryzen 9 7900X3D/7950X3D CPUs Are Excellent
The old engineered state of art was difsufsort but now there is libsais that makes use of prefetching (would be interesting to see how both react to huge caches). As for datasets, there are many classical ones. From rough order of size: Silesia Corpus, Manzini Corpus, Pizza&Chili Corpus, Large Text Compression Benchmark Corpus, etc.

The LZ4 introduced in PostgreSQL 14 provides faster compression
True.
If you're on your way down this rabbit hole, there's a bunch of old-machine-specific compression algorithms, developed by the emulator community, e.g. LZSA: https://github.com/emmanuel-marty/lzsa

Modern LZ Compression
There's quite a lot of retro modern LZ activity too! LZ turns out to be amazing on old machines, often only several times slower than a block copy. Optimal compressors and control over the algorithm have led to some very tight demos.
https://www.brutaldeluxe.fr/products/crossdevtools/lz4/index... LZ4 Data Compression - a rather long and in-depth article looking at LZ4 on the 65816 for the Apple IIgs
https://github.com/emmanuel-marty/lzsa - LZSA - a LZ4-like modern LZ that's more efficient both in speed and compression to LZ4 (at least on the 8 bitters it targets).
What are some alternatives?
wbz - A parallel implementation of the bzip2 data compressor in python, this data compression pipeline is using algorithms like Burrows–Wheeler transform (BWT) and Move to front (MTF) to improve the Huffman compression. For now, this tool only will be focused on compressing .csv files, and other files on tabular format.
