zlib::deflate_stream::tune

Fine tune internal compression parameters.

void
tune(
    int good_length,
    int max_lazy,
    int nice_length,
    int max_chain);

Compression parameters should only be tuned by someone who understands the algorithm used by zlib's deflate for searching for the best matching string, and even then only by the most fanatic optimizer trying to squeeze out the last compressed bit for their specific input data. Read the deflate.c source code (ZLib) for the meaning of the max_lazy, good_length, nice_length, and max_chain parameters.
