When evaluating LZ4 v1.8.3 Win64 against other standard compression utilities on a standard modern Windows Server architecture, the metric disparities become clear: Algorithm / Tool Compression Speed Decompression Speed Relative Ratio ~4900 MB/s LZ4 v1.8.3 High ( -9 ) ~5100 MB/s Zstandard v1.x (Default) ~1600 MB/s Gzip / Deflate Performance Takeaways
| | Compression Ratio | Compression Speed (MB/s) | Decompression Speed (MB/s) | | :--- | :--- | :--- | :--- | | memcpy (No Compression) | 1.000 | 13700 | 13700 | | LZ4 (Default) | 2.101 | 780 | 4970 | | Snappy (Google) | 2.091 | 565 | 1950 | | Zstandard (Level 1) | 2.883 | 515 | 1380 | | LZO 2.09 | 2.108 | 670 | 860 | | LZ4 HC (Level 9) | 2.721 | 41 | 4900 | | zlib (Level 1) | 2.730 | 100 | 415 | lz4 v183 win64
Enterprise database management systems run LZ4 on Win64 environments to compress Write-Ahead Logs (WAL) and transaction records before writing them to NVMe storage. Because the decompression speed is fast, data recovery operations introduce minimal latency. 2. Live Video Streaming Pipelines When evaluating LZ4 v1
