 The zstd distribution contains a tool called `zwrapbench` which can measure speed and ratio of zlib, zstd, and the wrapper.
 The benchmark is conducted using given filenames or synthetic data if filenames are not provided.

+The files are read into memory and processed independently.
 It makes benchmark more precise as it eliminates I/O overhead. 
 Many filenames can be supplied as multiple parameters, parameters with wildcards or names of directories can be used as parameters with the -r option.
 One can select compression levels starting from `-b` and ending with `-e`. The `-i` parameter selects minimal time used for each of tested levels.
