<DIV>Why DEF_MEM_LEVEL (along with Z_DEFAULT_COMPRESSION, -MAX_WBITS and
Z_DEFAULT_STRATEGY) gives better compression than MAX_MEM_LEVEL ?</DIV>
<DIV> </DIV>
<DIV>I compress 65471 bytes long buffers of general data and the output
buffer is always few bytes longer with MAX_MEM_LEVEL than with
DEF_MEM_LEVEL.<BR></DIV>
<DIV>How significant is performance gain when MAX_MEM_LEVEL is used?</DIV>
