 "Zstd" at its maximum compression level gives a compression ratio close to lzma,
lzham, and ppmx, and performs better than lza, or bzip2.Zstandard reaches the current Pareto frontier, as it decompresses faster than any other currently-available algorithm with similar or better compression ratio.Dictionaries can have a large impact on the compression ratio of small files, so Zstandard can use a user-provided compression dictionary.
