libdeflate is a library for fast, whole-buffer DEFLATE-based compression and decompression. It has support for the DEFLATE (raw), zlib (DEFLATE w/ zlib wrapper), and gzip (DEFLATE w/ gzip wrapper) formats. It is heavily optimized, and significantly faster than the zlib library, both for compression and decompression, and especially on x86 processors. In addition, libdeflate provides optional high compression modes that provide a better compression ratio than the zlib's {"level} 9\".
