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
That's really confusing since `pixz` exists and its "pixie" pronunciation actually works

Xz format considered inadequate for long-term archiving
pixz (https://github.com/vasi/pixz) is a nice parallel xz that additionally creates an index of tar files so you can decompress individual files. I wonder if dpkg could be extended to do something similar.

The best datahoarding hint that changed my live: use RAR archives (or any other archive format, really)
There's pixz, which indexes the tarball, allowing listing/extracting individual paths without decompressing the whole thing.

Hop: 25x faster than unzip and 10x faster than tar at reading individual files
Also relevant is pixz [1] which can do parallel LZMA/XZ decompression as well as tar file indexing.

7-Zip 21.0 alpha introduces native Linux support
Yes, it's as easy as installing pixz with symlinks pointing to xz (I think Debian even does this automatically as part of its post-installation scripts).

PeaZip 7.7.1 released!
Not quite what you're asking, but if you're a 7-Zip fan and on Linux, you might be interested in pixz.

Game Ready & Studio Driver 535.98 FAQ/Discussion
I don't think the GPU decompression optimizations is in this driver. I updated and using the Bulk Loader Demo test I'm actually seeing lower throughput than before. I used to hit around 24-25GB a sec, now I'm only hitting like 21GB a sec. Although it's possible but I doubt it, it could be related to the Windows 11 March update reducing SSD bandwidth. I haven't run the test in months so it might be related.

Pigz: Parallel gzip for modern multi-processor, multi-core machines
The data is compressed with GDeflate, not deflate. The single stream is designed to use the parallelism of a GPU. It is described here:
https://github.com/microsoft/DirectStorage/blob/main/GDeflat...
The GPU decompression benchmark I linked earlier allows you to specify a single file that it will compress with GDeflate (and zlib for comparison). The numbers presented in the docs that come with the benchmark and presented elsewhere are consistent with my own runs using a source file that is highly compressible.
Part of the trick of achieving this speedup is to read the data fast enough. I don't know of any NVMe drive that can reach full speed with a queue depth of 1. While running the benchmark in a windows VM with a GPU passed through, on the linux host I observed that the average read size was about 512k and the queue depth was sometimes over 30.

From Project Management to Data Compression Innovator: Building LZ4, ZStandard, and Finite State Entropy Encoder
We already have GDeflate, with permissive sources available for both CPU compression/decompression and GPU decompression in the DirectStorage GitHub repo. I haven't personally played with it yet, but I'll be implementing it in a project I'm working on in the next few months and am pretty excited to do so.

Samsung 990 Pro tested with DirectStorage. The Samsung 990 Pro, like the Sabrent Rocket 4 Plus-G and WD SN850X, has gaming / DirectStorage optimizations.
Only the final test where the results of several SSDs are displayed in the graph is a synthetic one. The first two both support DirectStorage and are designed with Microsoft's recommendations for DirectStorage in mind. That is, random reads of 32k or greater block sizes with high queue depths. This is because you need a high queue depth to be able to saturate NVMe drives.
