79 It has vastly slower compression speed and moderately slower decompression
80 speed.
85 It also has faster compression and decompression speed than zlib.
86 In the very high compression
88 settings, it does not offer quite as high a compression ratio as
90 However, its decompression speed does not suffer at high compression

135 typically around 3-5% of a final size of the compressed image.
139 runs in parallel to speed up compression.
