minus-square@[email protected]linkfedilink3•10 months agozstd may be newer and faster but lzma still compresses more
minus-squareGammalinkEnglish11•edit-210 months agoThought I’d check on the Linux source tree tar. zstd -19 vs lzma -9: ❯ ls -lh total 1,6G -rw-r--r-- 1 pmo pmo 1,4G Sep 13 22:16 linux-6.6-rc1.tar -rw-r--r-- 1 pmo pmo 128M Sep 13 22:16 linux-6.6-rc1.tar.lzma -rw-r--r-- 1 pmo pmo 138M Sep 13 22:16 linux-6.6-rc1.tar.zst About +8% compared to lzma. Decompression time though: zstd -d -k -T0 *.zst 0,68s user 0,46s system 162% cpu 0,700 total lzma -d -k -T0 *.lzma 4,75s user 0,51s system 99% cpu 5,274 total Yeah, I’m going with zstd all the way.
minus-square@[email protected]linkfedilink6•10 months agoNice data. Thanks for reminding me why I prefer zstd
minus-square@[email protected]linkfedilink1•10 months agodamn I did not know zstd was that good. Never thought I’d hear myself say this unironically but thanks Facebook

*Thank you engineers who happen to be working at Facebook
Very true, good point
As always, you gotta know both so that you can pick the right tool for the job.
