illusion new default algorithm compress LZ4-ZFS on SmartOS

A rough comparative analysis of LZ4 performance vs. LZJB:
  • Approximately 50% faster compression when operating on compressible data.
  • Approximately 80% faster on decompression.
  • Over three times faster on compression of incompressible data.
  • Higher compression ratio (up to 10% on the larger block sizes).
  • Performance on modern CPUs often exceeds 500 MB/s on compression and over 1.5 GB/s on decompression and incompressible data (per single CPU core).
