First, tar + gzip compresses better than zip, since the compression of the next file can use history from the previous file (sometimes referred to as a "solid" archive). zip can only compress files individually. detroit edison bill payment The maximum compression ratio of the deflate format is 1032:1. This is because the longest run that can be encoded is 258 bytes. At least two bits are required for each such run (one bit for the length code and one bit for the distance code), hence 4*258 = 1032 uncompressed bytes can be encoded per one compressed byte.GZIP is the current standard for file compression on the web.
