   Re:  PKZIP FOR OS/2
 
Loren,
 
Noted your bulletin about OS/2 et al.  I just received the OS/2 stuff
the other day.  I would fully expect that PKZIP 1.0 will be released
with both MS-DOS and OS/2 versions!  BTW, here is some tests of PKZIP
1.0 alpha:
 
CV.EXE        Original Size 232896 bytes    MSC 5.1 CodeView
 
              Compressed Size    Compress Time     Extract Time

PKZIP 0.92        140685             14.76             3.52
LHARC             133911             28.08            15.08

PKZIP 0.92         25018             10.68             1.44

PKZIP 0.92        110533             38.32             4.62
LHARC             103245             64.18            11.12
PKZIP 1.0 Alpha    95424             49.10             3.20

As you can see, PKZIP 1.0 Alpha is compressing up to twice as
fast as LHARC, but moreover is compressing better than LHARC
in every case.  Also, the extraction times are up to 5 times
faster than LHARC too.
