![]() Manpage: want to safe disk space? have got the time? xz! # time to decompress without pigz (not supported): # time to compress without pigz: # real 13m13.490s # (have 25MByte/sec during compression and over 100MByte/sec during decompression) # decompression seems to use way less CPU resources than compression # multi threaded decompress is not implemented # size of home directory was compressed by -70% to 8.5 GByte # took 6min to compress a 29 GByte home directory # time meassures the time it needed using all cores Time tar -c -use-compress-program=pigz -f directory # create tar archive using pigz as "compressor" To get multi core usage for compression (faster) the user tells tar to use a different compression algorithm that has multi-core support like pigz or xz. Tar might be old, but still a great program for archiving files Tar gz (single core) -> tar pigz (multi core) GNU Linux bash – howto making tar use multiple cpu cores when compressing a directory – multi threaded compression decompression with pigz (faster) and xz (tighter) Volunteer computing / World Community Grid / WCG.Virtualization / KVM / VirtualBox / xenserver.USV / UPS / Power / PowerSupply / Energie.Space / Cosmos / Kosmos / Galaxy / Galaxie / Weltall.raspberry / carambola / atmel / embedded linux.Propaganda / FakeNews / InfoWars / InformationWarfare.project management / project planing / git.Privacy Protection / Datenschutz / DSGVO / GDPR.Privacy / convenience vs surveillance / Orwell.Photographie / Photography / Foto / Pictures / Pics. ![]() ![]() Innovation / Civilisation / Zivilisation / Culture.gute nachrichten / good news / positive news.Free Hardware / OpenBios / OpenFirmware / CoreBoot / LibreBoot.database / MariaDB / MySQL / Postgress / DB.CyberSec / ITSec / Sicherheit / Security / SPAM.
