Zstd 1.5.7 Pushing Compression Performance Even Further

([Free Software] 6 Hours Ago Zstandard 1.5.7)


Zstandard 1.5.7 was released a short time ago as the newest update to this widely-used compression algorithm backed by Meta. Zstd 1.5.7 packs more than 500 commits, including new performance optimizations and other enhancements.

On the performance side, Zstd 1.5.7 brings better compression speed when using small data blocks... 4KB block size around 10% faster while 32KB block sizes are around 20% faster, +12% for 64KB, and then falling down to +5% for 128KB block sizes. Some nice gains with the updated Zstd for those using small block sizes:

There is also performance improvements around dictionary compression, up to 4.9x faster performance with "--patch-from" improvements, and compression ratio improvements for lage files.

Zstd 1.5.7 also brings command-line option upgrades with a new "--max" compression option for those really wanting to pursue maximum compression. Plus a variety of bug fixes incorporated over the past year.

Zstd 1.5.7 can be downloaded from [1]GitHub . Now to hope that the in-kernel-tree Zstandard implementation is updated against Zstd 1.5.7 in a timely manner...

Certain passages in several laws have always defied interpretation and the
most inexplicable must be a matter of opinion. A judge of the Court of
Session of Scotland has sent the editors of this book his candidate which
reads, "In the Nuts (unground), (other than ground nuts) Order, the expression
nuts shall have reference to such nuts, other than ground nuts, as would
but for this amending Order not qualify as nuts (unground) (other than ground
nuts) by reason of their being nuts (unground)."
