********** ARCHIVE COMPARISON TEST (A.C.T.) - NOVEMBER 1995 ********* * Author: JEFF GILCHRIST * *********************************************************************** * A.C.T. may be re-posted or distributed only if the contents are * * not changed under any circumstances and the contents are posted * * in their entirety. * *********************************************************************** ########################### PLEASE READ ############################### A.C.T. is now on the World Wide Web (WWW)! It can be accessed at: http://www.mi.net/act/act.html This is the best way to view A.C.T. since it is in a graphical format and most authors have a link to their e-mail address. There are also links to FTP sites to download most of the archivers. Finally, there is a link to my e-mail address to send me any comments or suggestions. ####################################################################### The following is a test I did on several archivers to compare their performance against others. For the following tests with single file types, I used a 486DX4-75 with 8 megabytes of RAM. No disk CACHE was used at all! For the timing, Ultra Precision Command Timer v1.6 by Erik de Neve was used. The operating system used was DOS 6.22. I compressed the tested files from my hard drive to a 2 megabyte RAM drive. *** PART 1 - SINGLE FILE TESTS *** TEXT File Test - Uncompressed Size 768,771 bytes ARCHIVER SWITCHES CREATION TIME COMPRESSED SIZE RATIO -------- -------- ------------- --------------- ----- B X1 0.94a ->X xem4l2 0 m 31.3 sec 219,652 bytes 71.4% X1 0.94a ->X xem4l1 0 m 32.2 sec 219,734 bytes 71.4% ACB 1.13b f 2 m 36.2 sec 227,267 bytes 70.4% N ACB 1.14a f 2 m 36.8 sec 227,416 bytes 70.4% HA 0.999b e2 0 m 34.1 sec 235,767 bytes 69.3% BSArc 2.0.0 -++ 0 m 46.7 sec 244,049 bytes 68.3% CODEC 3.21 -c10 0 m 41.5 sec 252,375 bytes 67.2% NO HAP 4.0 BETA 3 0 m 13.2 sec 260,103 bytes 66.2% HAP 3.14e11 3 0 m 14.1 sec 260,103 bytes 66.2% QUANTUM 0.96 -c5 9 m 42.6 sec 271,960 bytes 64.6% QUANTUM 0.96 (none) 1 m 37.0 sec 287,179 bytes 62.6% HPACK 0.79a0 -df 0 m 48.5 sec 299,072 bytes 61.1% X1 0.94a ->X xe 0 m 49.9 sec 299,900 bytes 61.0% ARJZ 0.15 -mp9 -jh 0 m 27.2 sec 301,771 bytes 60.7% UC2 v3.0 PRO (Max Compress) 0 m 35.4 sec 302,022 bytes 60.7% ARI 1.12 -n 2 m 20.5 sec 302,200 bytes 60.7% N LHARK 0.3e -tob 0 m 30.5 sec 302,820 bytes 60.6% LHARK 0.1c -tob 0 m 29.3 sec 303,562 bytes 60.5% ARJZ 0.15 (none) 0 m 18.0 sec 304,182 bytes 60.4% YAC 1.02 (none) 0 m 32.1 sec 307,929 bytes 59.9% LHARK 0.1c (none) 0 m 14.8 sec 308,880 bytes 59.8% N LHARK 0.3e (none) 0 m 14.2 sec 309,326 bytes 59.8% LIMIT 1.2 -mx 0 m 21.2 sec 310,872 bytes 59.6% LIMIT 1.2 (none) 0 m 19.6 sec 311,187 bytes 59.5% AMGC 2.2 -mm 0 m 50.2 sec 311,279 bytes 59.5% UC2 v3.0 PRO (Default) 0 m 17.4 sec 311,412 bytes 59.5% HA 0.999b e1 0 m 26.4 sec 312,016 bytes 59.4% X1 0.93d ->HA xem1 0 m 32.0 sec 312,016 bytes 59.4% SQZ 1.08.3 -q(ALT236) 0 m 26.3 sec 312,330 bytes 59.4% INFO-ZIP 2.0 -9 -j 0 m 18.0 sec 312,371 bytes 59.4% WINZIP95 6.0 (Max Compress) 0 m 19.6 sec 312,371 bytes 59.4% PKZIP 2.04g -ex 0 m 14.8 sec 312,604 bytes 59.3% RAR 1.55 -ep -m5 0 m 29.6 sec 312,726 bytes 59.3% GZIP 1.2.4 -9 0 m 23.0 sec 312,915 bytes 59.3% GZIP 1.2.4 (none) 0 m 12.9 sec 313,379 bytes 59.2% INFO-ZIP 2.0 -j 0 m 14.6 sec 313,466 bytes 59.2% CODEC 3.21 (none) 0 m 15.9 sec 313,787 bytes 59.2% BSArc 2.0.0 (none) 0 m 19.1 sec 314,138 bytes 59.1% AIN 2.2 /m1 0 m 10.4 sec 314,299 bytes 59.1% SQZ 1.08.3 (none) 0 m 18.2 sec 315,028 bytes 59.0% RAR 1.55 -ep 0 m 16.4 sec 315,851 bytes 58.9% PKZIP 2.04g (none) 0 m 10.2 sec 316,113 bytes 58.9% QUARK 1.0beta (none) 0 m 17.7 sec 317,195 bytes 58.7% AIN 2.2 (none) 0 m 08.3 sec 317,659 bytes 58.7% WINZIP95 6.0 (Normal Comp) 0 m 10.5 sec 318,344 bytes 58.6% ARJ 2.42c BETA -jm -e 0 m 16.7 sec 318,939 bytes 58.5% ARJ 2.42c BETA -e 0 m 15.4 sec 319,172 bytes 58.5% ARJ 2.41a -jm -e 0 m 17.0 sec 318,939 bytes 58.5% ARJ 2.41a -e 0 m 15.7 sec 319,172 bytes 58.5% AMGC 2.2 (none) 0 m 16.7 sec 327,646 bytes 57.4% NULIB 3.24 c5 0 m 06.0 sec 334,187 bytes 56.5% LHA 2.55b -we: 0 m 17.0 sec 339,110 bytes 55.9% AR 0.02 (none) 0 m 30.7 sec 339,118 bytes 55.9% SAR 1.0 (none) 0 m 31.8 sec 339,118 bytes 55.9% ZOO 2.10 h: 0 m 30.1 sec 339,245 bytes 55.9% PUT 3.41 (none) 0 m 21.5 sec 339,642 bytes 55.8% HYPER 2.5 (none) 0 m 09.8 sec 345,887 bytes 55.0% PAK 2.51 (none) 0 m 10.9 sec 347,608 bytes 54.8% N DWC 5.10 z 0 m 05.8 sec 362,629 bytes 52.8% SQWEZ 2.2 /s 0 m 31.0 sec 365,224 bytes 52.5% ARX 1.0 (none) 0 m 10.3 sec 369,545 bytes 51.9% N DWC 5.10 (none) 0 m 05.6 sec 380,228 bytes 50.5% DWC 5.01 (none) 0 m 09.0 sec 380,301 bytes 50.5% TSCOMP 1.3.21 -sh 0 m 13.1 sec 391,252 bytes 49.1% MDCD 1.0 (none) 0 m 05.8 sec 391,703 bytes 49.0% ZOO 2.10 : 0 m 13.0 sec 391,750 bytes 49.0% JRCHIVE 1.10 -v 0 m 09.6 sec 416,982 bytes 45.8% TSCOMP 1.3.21 -sm 0 m 11.3 sec 418,014 bytes 45.6% F ARC 6.02 (none) 0 m 05.3 sec 418,511 bytes 45.6% NULIB 3.24 (none) 0 m 07.1 sec 454,304 bytes 40.9% Winner for best compression : X1 0.94a B Winner for fastest compression: ARC 6.02 F Winner for best overall : HAP 4.0 BETA O N Indicates a new version of the software tested since the last posting of these tests.

EXE Pack File Test - Uncompressed Size 341,444 bytes The EXE Pack test compares programs that compress .EXE files and still allows them to execute. The .EXE file used in this test is GWS.EXE found in The Graphic Workshop v7.0e by Alchemy Mindworks Inc. The UNCOMP. TIME data shows the amount of time it takes to uncompress and run the executable file. This time was calculated using a utility called BENCH 0.01beta written by Michal Weis (weis@elf.stuba.sk). The results for ACB, RAR and PKZIP are listed only to show how normal archivers compression ratios compare with EXE Packers. UNCOMP. ARCHIVER COMP.

I used a 486DX4-75 with 8 megabytes of RAM to do this test. No disk CACHE was used at all! For the timing, Ultra Precision Command Timer v1.6 by Erik de Neve was used. The operating system used was DOS 6.22.

If you cannot access the WWW then most of the archivers can be found on the following four FTP sites. Try them in this order: ftp.elf.stuba.sk /pub/pc/pack (6 Anonymous Users 13:00-06:00 GMT) ftp.kiae.su /msdos/arcers (20 Anonymous Users Allowed) ftp.coast.net /SimTel/msdos/archiver (400 Anonymous Users Allowed) garbo.uwasa.fi /pc/arcers (100 Anonymous Users Allowed) ------------------------------------------------------------------------ As you may or may not have noticed, I have been releasing these test results about once a month. I have decided to release the results on the first day of each month and name these tests A.C.T. * Please note that the best overall selection is based entirely on the archiver's compression/speed ratio. It is NOT based on the reliability, price, technical support or the options available in the archiver. I have decided to add an Options List which shows what archivers support certain major options. If you think I should add another category to the list or you see an error, please let me know. If there is an error, please tell me what switch will activate the command that I missed. ---------------------------- OPTIONS LIST ------------------------------ MULTI MANAGE DISK AUTH.

This is not nearly as nice as multi-disk spanning. - INFO-ZIP comes with a utility called ZIPSPLIT which does the same thing as UC2's SAS utility. % - UC2 uses shared dictionaries between file collections to utilize similarities between files. -------------------------------- INDEX ---------------------------------- ARCHIVER RELEASE AUTHOR & (INTERNET E-MAIL) -------- ------- ------------------------------------------------------ TYPE PLATFORMS SUPPORTED FREE UNCOMPRESS ---------- --------------------------------- --------------- ACB Sep '95 George Buyanovsky (george@acb.alma-ata.su) v1.14a Freeware DOS Yes AIN Jul '94 Transas Marine (UK) Ltd.

ACB 1.14a - ACB increases it's compression ratio again. As usual, the new version is not compatible with older versions of ACB. For more info, e-mail: george@acb.alma-ata.su FTP: ftp.elf.stuba.sk /pub/pc/pack/acb14a.zip DWC 5.10 - This is not a new version, but newer than I had before. Thanks to David Mulligan for sending me this version. Some bug fixes and small changes in this version. For more info, e-mail: dwcooper@ix.netcom.com FTP: ftp.elf.stuba.sk /pub/pc/pack/dwc-a510.exe HAP 4.0beta - This new version of HAP is faster and has been optimized for graphical files. Compared to the other leading archivers on the .BMP test, HAP is #1 and it is MUCH faster. Please note that this is just a PRE-RELEASE version. It is NOT publicly available. No uncompressor for the new version is available yet, hence no timing data. It is possible to Add, List, Delete, and Test archives with previous versions of HAP but you cannot always extract files. An extractor is in the works and there will also be a switch added to v4.0 to create the old 3.14e11 compatible archives. For more info, e-mail: feldmann@xs4all.nl LHARK 0.3e - This new archiver uses the -lh7- compression method and can create compatible versions with LHA. As of now, LHA cannot uncompress files created with the -lh7- method. New in this version is: SFX, extended LHA headers, now uses exact memory requirements, file encryption For more info, e-mail: digi@mozcom.com FTP: ftp.elf.stuba.sk /pub/pc/pack/lhark03e.exe ----------------------------------------------------------------------- Anyone wishing to send me updated versions of archivers or email may use PGP (Pretty Good Privacy) v2.6 or above to encrypt the info.
