Why is ZLIB_COMPRESSION_OVERHEAD soooo big?

How knows why zlib needs more 3/4 of my RAM per default? What's the minimum ZLIB_COMPRESSION_OVERHEAD ?

decompress.c:

78 #ifdef CYGOPT_REDBOOT_FIS_ZLIB_COMMON_BUFFER 79 # define ZLIB_COMPRESSION_OVERHEAD CYGNUM_REDBOOT_FIS_ZLIB_COMMON_BUFFER_SIZE 80 #else 81 # define ZLIB_COMPRESSION_OVERHEAD 0xC000 82 #endif

Would zlib work with 0c8000?

Thanks Oliver Munz
