WinZip reaches a good compression ration on the test data with ZIPX format creating a 70,70MBoutput archive, followed by PeaZip with ARC format at 71,70MB - with ARCoutperforming 7Z and ZIPX in terms of compression speed, takingonly about half the time. Then, same operations are repeated on a slower mechanical disk, wherehard disk read / write speed may become a limiting factor: benchmarkinput data is saved to external disk (USB3 HDD) andcompressed to same external disk, same partition, separate directory resulting archivesare extracted toseparate directory on same (external) disk/partition.Įach compression and extraction test is repeated 10 times to get anaverage value size is expressed in MB, time in seconds.Įach archiving utility performance is tested working with zip and atleast anotherarchive format.įor pure compression formats (Brotli and Zstandard) requiring toconsolidate the multiple input files of the benchmark into a single TARfile, are shown both pure compression and extraction speeds - which arethe actual speed for a single file input, and are the values reportedin the graphs - and, in brackets (), the total operation time taking inaccount tar / untar operations, with performance penalty being almostnegligible on fast SSD disk.īenchmark resultstable, the lower the better for all columns UtilityĬompression ratio results:what application compresses betterĬompressingdata to ZIP format,which is read / write supported by all all archiving applicationstested in this benchmark, all utilities reach a compression ratio inthe order of 33%, with WinZip reaching best compression for ZIP archiveat 97,10MB but at the cost of much slower compression speed.ħ-Zip and PeaZip (which uses the same optimized Deflate algorithm of7-Zip) attains good compression in zip format with 97,70MB atintermediate speed, whileWinRar and Bandizip reach the lowest compression at 100MB and 101 MBrespectively, but with significantly higher compression speed.Īn exception is ZIP compressed with BZip2method (a preset available in PeaZip) which reduces input size down to83 MB, result much closer to strong compression formats (as rar and 7z)than to ZIP files compressed with Deflate method.īrotli and Zstandard (both at defaultcompression level 3) provides compression ratio in the same range ofZIP, comparing favourably in terms of speed.Ĭompressing in formats alternative to ZIP allows all tested archivingapplications to reach a better compression ratio, roughly grouped at25%. Benchmarkinput data is saved to system disk (PCIe SSD) and compressed to systemdisk, same partition, separate directory the resulting archives arethen extracted toseparate directory on same (system) disk/partition.
