    What is the difference between bt2, bt3, and bt4b?

    Which one compresses the most? Can bt2 be better than bt4b on some files?

      bt2 - hash by 2 bytes.
      bt4 - hash by 4 bytes.
      bt4b - hash by 4 bytes with big table.

      > Which one compresses the most?
      Compression ratio almost the same.

      Yes, and vice versa.
