hi,I use your open source for gzip,but i want to use best compression,so i change parms use best compression,but data isn't less than use default compression,
as:
define Z_NO_COMPRESSION 0
define Z_BEST_SPEED 1
define Z_BEST_COMPRESSION 9
define Z_DEFAULT_COMPRESSION (-1)

There's no guarantee that Z_BEST_COMPRESSION will make the file smaller, just that it won't make it bigger.
