used in Unix compress(1) and in the GIF image format, the compression method
currently used in zlib essentially never expands the data. (LZW can double or

independent of the input data and can be reduced, if necessary, at some cost
in compression.")

redundancy reduction to improve the subsequent compression ratio of
larger files.  It can then further compress the result with the ZPAQ or
LZMA algorithms for maximum compression, or LZO for maximum speed.  This
choice between size or speed allows for either better compression than
even LZMA can provide, or a higher speed than gzip while compressing as
well as bzip2.")

aim for maximum compression, or compatibility with any other compression library;
instead, it aims for very high speeds and reasonable compression. For instance,
compared to the fastest mode of zlib, Snappy is an order of magnitude faster
for most inputs, but the resulting compressed files are anywhere from 20% to
