Description

LZ4 is a new high-speed BSD-licensed compression algorithm written by Yann Collet that delivers very high compression and decompression performance compared to lzjb (>50% faster on compression, >80% faster on decompression and around 3x faster on compression of incompressible data), while giving better compression ratio. For detailed benchmark numbers see the attached spreadsheet.
As such, this algorithm seems like a good candidate to integrate into Illumos' ZFS.
