The v183 release utilizes advanced vectorization flags in MSVC (Microsoft Visual C++) and MinGW. It aligns memory buffers to 64-byte boundaries. This alignment enables the CPU to use SIMD (Single Instruction, Multiple Data) instructions for fast memory copying during decompression. Technical Specifications and Benchmarks
LZ4 v1.8.3 decompresses data at speeds bounded primarily by the RAM bandwidth or NVMe SSD read limits. lz4 v183 win64
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.
