Zstandard (zstd) 1.5.7

Zstandard is a fast compression algorithm providing high compression ratios. It offers a very wide range of compression/speed trade-offs, while being backed by a very fast decoder.

Features

• Real-time compression: Suitable for scenarios where compression speed is critical
• High compression ratios: Comparable to zlib with significantly faster compression
• Wide range of levels: From ultra-fast to maximum compression
• Small data optimization: Special mode for compressing small data chunks
• Dictionary compression: Enhanced compression for repetitive data patterns
• Streaming support: Compress and decompress data streams

Applications

Zstandard is designed for modern systems and is particularly well-suited for:

• Real-time backup systems
• Network data transfer
• File compression utilities
• Database compression
• Container image compression

Performance

Zstandard provides significantly better compression ratios than lz4 and much faster compression than zlib, making it an excellent general-purpose compression algorithm for a wide range of use cases.

Included Programs

• zstd: Main compression/decompression utility
• zstdcat: Decompress to stdout (link to zstd)
• zstdgrep: Run grep on compressed files
• zstdless: Run less on compressed files
• zstdmt: Multi-threaded version (link to zstd)
• unzstd: Decompression utility (link to zstd)

Library

The package includes the libzstd shared library, allowing other applications to use Zstandard compression capabilities.
