As the table shows:
However, it's crucial to realize that these numbers are for reference only. Real-world performance depends heavily on the hardware, the specific file type being compressed, and the chosen compression level. For more targeted benchmarking on your own system, the lz4.exe utility includes a built-in benchmark module. You can use it like this: lz4 -b1e18i1 , which tests compression levels starting from 1 up to 18 for a duration of 1 second each.
LZ4 is a lossless compression algorithm that belongs to the LZ77 family (named after Abraham Lempel and Jacob Ziv, 1977). It was created by Yann Collet in 2011, targeting scenarios where compression speed must rival memcpy(). lz4 v183 win64
When you download the Win64 binaries for v1.8.3, you typically find:
While the LZ4 project has moved on to newer versions like 1.10.0, version 1.8.3 holds a specific place in the timeline as a critical bugfix release. It was built upon the foundation of the v1.8.x series, which introduced performance improvements in decompression speed compared to earlier versions like v1.7.3. As the table shows: However, it's crucial to
The integrated benchmark tool ( -b flag) received updates to accurately calculate hardware-level throughput on modern multi-core Windows servers, avoiding skew from Windows thread scheduling policies. 4. Installation and Setup on Windows 64-bit
To understand LZ4's strengths and weaknesses, it's helpful to place it alongside its modern competitors. The most common comparison is with , Snappy , and the classic gzip (zlib) . You can use it like this: lz4 -b1e18i1
Once extracted, the lz4.exe CLI is simple to use, supporting gzip-like arguments. It's a good practice to place the executable in a directory that is listed in your system's PATH environment variable, or simply run it from the directory where it resides.
