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 joined together.

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.

#### Compatibility issues
|
||||
After enabling zstd compression not all native zlib functions are supported. When calling unsupported methods they put error message into strm->msg and return Z_STREAM_ERROR.
