minus-squaremenaslinkfedilinkEnglisharrow-up16arrow-down1·4 days agohaha. I spent so much time looking for an efficient compression algorithm for audio and movies … until I finally understood there are already compressed X) However it allow me to discover zst, wich is uncredible with text : 35M test.log 801K test.7z 32 test.log.7z 46 test.log.tar.bz2 45 test.log.tar.gz 108 test.log.tar.xz 22 test.log.tar.zst 2,1M test.tar.bz2 8,1M test.tar.gz 724K test.tar.xz 1,1M test.tar.zst 8,1M test.zip
minus-squaresobchak@programming.devlinkfedilinkarrow-up8·3 days agoYeah, I found zst recently as well. Quite a bit faster than xz/7z which is what I previously used (or gz when I just needed something fast).
minus-squareUnrepentantAlgebra@lemmy.worldlinkfedilinkarrow-up10·3 days agoAm I reading that correctly that test.log.7z compressed 35 mB of text into 32 bytes?
minus-squarerbn@sopuli.xyzlinkfedilinkarrow-up7·3 days agoAnd .tar.zst into 22!? What was that log file? Millions of identical characters?

minus-squaremenaslinkfedilinkEnglisharrow-up2·3 days agoI shall have check. No for some reason some archives failed. Not 7z, but it size is 800kB : 35M test.log 804K test.7z 8,1M test.tar.gz 8,1M test.zip 724K test.tar.xz 2,1M test.tar.bz2 1,1M test.tar.zst
