About Zstandard

Zstandard is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.

What's new in 1.5.7

Zstandard v1.5.7 is a significant release, featuring over 500 commits accumulated over the past year. This update brings enhancements across various domains, including performance, stability, and functionality, and is particularly recommended for 32-bit users due to a bug fix detailed below. edit: man pages were not properly updated in this package, and are still pointing to v1.5.6. If you want the v1.5.7 version, they are updated in dev branch, and can be cherry-picked using commit 6af3842. Alternatively, they can also be built locally using make manual and make -C programs man. Performance Enhancements Enhanced Compression Speed for Small Data Blocks The compression speed for small data blocks has been notably improved at fast compression levels, thanks to contributions from @TocarIP, further extended in #4165. Below are benchmark results illustrating the performance improvements for level 1 compression on the Silesia corpus, segmented into different block sizes: ──────────┬────────┬────────┬─────── Block Size│v1.5.6 │v1.5.7 │Improv. ──────────┼────────┼────────┼─────── 4 KB │280 MB/s│310 MB/s│+10% ──────────┼────────┼────────┼─────── 8 KB │328 MB/s│364 MB/s│+11% ──────────┼────────┼────────┼─────── 16 KB │360 MB/s│396 MB/s│+10% ──────────┼────────┼────────┼─────── 32 KB │383 MB/s│458 MB/s│+20% ──────────┼────────┼────────┼─────── 64 KB │423 MB/s│474 MB/s│+12% ──────────┼────────┼────────┼─────── 128 KB │460 MB/s│485 MB/s│+5% ──────────┴────────┴────────┴─────── These improvements are particularly beneficial in data centers and databases, where data is often divided into...
