Greg,

Actually the ung.c you have is not meant for speed comparisons.  I have 
another version that is that I will post tonight.  The one you have 
uses buffered i/o, whereas the one I will post uses direct i/o (as does 
gzip).  I have tested that newer ung.c using both the new inflate and 
the new crc code and realized a 60% increase in speed over gzip 1.3.3.
