lz4

LZ4 is a high-performance lossless compression algorithm designed to offer extremely fast compression speeds exceeding 500 MB/s per core and even faster decompression speeds that can reach RAM limits in multi-core systems. It allows dynamic tuning of speed versus compression ratio while also providing a high compression variant (LZ4_HC) that optimizes for improved compression at the cost of CPU time. Additionally, LZ4 supports dictionary compression to enhance performance on small files, making it versatile for various data compression tasks.
