Subject: SUMMARY: Four tests of 19 MSDOS archivers and 6 file compressors
Message-ID: <C1ApnM.73p@mentor.cc.purdue.edu>
Sender: news@mentor.cc.purdue.edu (USENET News)

DISCLAIMER:
----------
Your results could be quite different from mine due to factors
such as disk speed, disk fragmentation, disk caching, RAM size and
TSRs loaded.
SUMMARY:
-------
The fastest archiver and de-archiver were PKZIP 2.04c and its
companion PKUNZIP. The greatest compression was achieved by ha 0.98
although it was the second slowest (trailed only by "scrnch").
RESULTS:
-------
The following four tests were run on a DFI 486/33 EISA with a Fujitsu
500M drive (disk caching disabled) with 8 Meg of RAM running DOS 5.0.
No TSRs were loaded. Times are rounded to the nearest second.
Test 1: 42 files, ~2.28 Mbytes, simulates full disk backup
Test 2: 88 files, ~0.71 Mbytes, small ".bas" and ".pas" files
Test 3: 11 files, ~1.05 Mbytes, ASCII word processing output
Test 4: 17 files, ~1.19 Mbytes, various graphics formats
Archivers tested:
arc 6.02 arj 2.30 arj 2.39a dwc a5.01
ha 0.98 hpack 0.75 hpack 0.78 hyper 2.5
lha 2.13 pak 2.51 pkpak 3.61 pkzip 0.92 *
pkzip 1.1 * pkzip 1.93 * pkzip 2.04c ** sqz 1.08
zip 1.9p1 *** zoo 2.00 zoo 2.10
* = unzipped with pkzip 1.1's pkunzip
** = unzipped with pkzip 2.04c's pkunzip
*** = unzipped with Info-Zip's unzip
Compressors tested:
compress diet 1.44 huf sqpc 1.31
scrnch
File storage tools tested (also archivers w/"store" option):
arj 2.30 arj 2.39a cpio ha 0.98
pkzip 2.04c tar zip 1.9p1
I can provide details on the amount of compression for each of the files in
each of the tests, but I haven't included it in this posting because the
article length would become excessive. (Those details and the contents
of this file are currently stored in a QPRO 4.0 ".wq1" file where I can
sort the various columns with ease.)
REQUEST:
-------
If you know of any archivers/compressors that I can readily add to my
test suite, please contact me at one the following address.
