About:
LZ4 is a lossless compression algorithm that is extremely fast, offering compression speeds up to multiple GB/s per core. It features an extremely fast decompressor, often exceeding RAM speeds in certain scenarios. This makes it ideal for performance-critical applications where data throughput is a priority.
Key Features:
  • Extremely fast compression and decompression speeds
  • High compression ratio comparable to zlib
  • Large block format (LZ4F) supporting dictionary compression
  • BSD 2-Clause License
Use Cases:
  • Real-time data logging and streaming
  • Database and file system compression
  • Network protocol optimization
  • Game engine asset loading
Alternatives:
  • zstd – Zstandard offers higher compression ratios at the cost of speed, whereas LZ4 prioritizes raw throughput.
  • gzip – Gzip is ubiquitous but significantly slower than LZ4 in both compression and decompression.
