Please consider using -DNO_GZIP in zlib version 1.2.5 (April 19, 2010) from http://zlib.net/ . Compiling zlib with -DNO_GZIP forces adler32 as the checksum algorithm instead of crc32, and zlib streams for the data format instead of gzip streams. adler32 is significantly faster, less energy intensive, and several kilobytes smaller in static size because it uses no CRC table. The cost is a loss of at most 0.023% in detecting corruption. -- John Reiser, jreiser@BitWagon.com
