Here are the results of tests performed in March 2002 to compare lossless compression of "binary" files by all known good enough programs developed for such purpose, including RK, DC, YBS, Bzip2, RAR, ACE and 7-zip. See Archive Comparison Test by J.Gilchrist for more details: http://compression.ca If anybody wants to start or continue such tests, or can suggest some other sets of files, or other compression programs, (not sources or algorithm descriptions, executable programs only) or knows we have missed something important, (some new fantastic technology, an algorithm or even a program capable of lossless compression of up to 1000:1 etc.) please let us know immediately: artest@inbox.ru Thank you!

Compression time is divided by 10 here, because more than 90% of people would never compress anything during their life (with compression programs), but they use compressed data almost _every_ time they use computers and/or Internet. That's why compression time is not so actual for them.[[3]] Details

Some old or less efficient programs will not be tested next time: UFA, BIX, ACB, BA, BEE, PPMy.WARNINGS:
ACB refuses to take files shorter than 257 bytes. About 400 such files were processed with "rar a -m0 name.acb name.bin" (see do_acb_u.bat and do_acb_r.bat in artest19.zip). BA 1.00beta5 can't losslessly decompress many files: CUN5IF~1.bin, CUN6IF~1 etc It says nothing like "CRC fails". BEE can't decompress some files compressed in "solid" mode. DC 0.99.158b fails to decompress HLPCOPY..bin, but only if you compress with "-mb5" switch and [<output>] filename like "any.dc5". Says nothing like "CRC fails". SBC is the only compressor converting "non-portable" symbols like "+", "&", "$" or "," to "_". Inconvenient feature. Problems in all other compressors were not found.
