Compressing files

  • xz -1 is reasonably fast and compresses much better than gzip -9
  • zstd seems to be one of the fastest algorithms.
  • Some people think xz is inadequate for long-time file archiving.
  • 7z has integrated AES256 encryption.

Benchmarks

  • Quick Benchmark: Gzip vs Bzip2 vs LZMA vs XZ vs LZ4 vs LZO (CatchChallenger Wiki)
  • Centminmod Forums: Compression Comparison Benchmarks: Round 3 (Archive), Round 4
    • Comparing 11 different compression algorithms:
      • zstd v1.4 - Facebook developed realtime compression algorithm here. For –format=lz4 using lz4 v1.9.0
      • brotli v1.0 - Google developed Brotli compression algorithm
      • gzip v1.5
      • bzip2 v1.06
      • pigz v2.4 - multi-threaded version of gzip
      • pbzip2 v1.1 – multi-threaded version of bzip2
      • lbzip2 v2.5– multi-threaded version of bzip2
      • lzip v1.21 – based on LZMA compression algorithm
      • plzip v1.8 – multi-threaded version of lzip
      • xz v5.2
      • pxz v5.2 - multi-threaded version of xz
