      Thought 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.

      As always, you gotta know both so that you can pick the right tool for the job.
