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 1.0 Alpha 133778 13.54 2.98
---------------
MANUAL.DOC Original Size 73445 bytes PKZIP 0.92 doc file
Compressed Size Compress Time Extract Time
--------------- ------------- ------------
PKZIP 0.92 25018 10.68 1.44
LHARC 22643 20.26 2.98
PKZIP 1.0 Alpha 21211 14.42 1.22
---------------
QMODEM.DOC Original Size 311005 bytes Qmodem 3.1 doc file
Compressed Size Compress Time Extract Time
--------------- ------------- ------------
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.
