LZ4 for ZFS

IllumOS update

Look what just happened last night:

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.

  • Status changed from New to Closed

What does it mean?

In plain english, the latest IllumOS kernel has LZ4 compression available for the ZFS filesystem.
