    which is completely pointless since blocks are written randomly and blocks from the same file aren't necessarily contiguous

    Sorry but ZFS does not preform what will be allocated using exact size of the block.
    ZFS additionally has dynamic allocation using (record) which is from 1Kb up to 16MB.
    variable block size is only reducing but not solving the fragmentation.

    So you want to say that you don't know that COW transforms small random write IOs into sequential one?
    Not sure how this is relevant with fragmentation

    If you need Solaris you can use it for free.
    Paid is support.
    Ah, so it's like Windows 10 then, mostly closed source but at least gratis. Good to know.

      It sure was in the last benchmarks before that went up.

      I don't know do you know that but after Sun was taken over by Oracle now only on Solaris kernel is working more people than during Sun time on entire Solaris distribution.
      Every few months/SRUs is released batch of new features (I'm talking about only changes in kernel space).
      Lies, people has been laid off and information about the situation also hit the streets

        Sorry how did you get that?
        ZFS is not writing blocks in random locations
        Again you are guessing.

        variable block size is only reducing but not solving the fragmentation.
        Nope. It reduces amount of metadata about what is allocated. It reduces as well number of IOs
        Again you are using intuition not hard knowledge.

        Not sure how this is relevant with fragmentation
        It is not at all because none of the ZFS users cares about fragmentation

        ]Ah, so it's like Windows 10 then, mostly closed source but at least gratis. Good to know.
        Nope. Windows has nothing to do with ZFS.
        Really ZFS is so different that whatever other experience you have it cannot be extrapolated on its area

          Last -> you mean 19 years ago ..
          How old are you? (ruffly +/-5 years)

            You will gain small amounts of performance if you change to "compress-force=zstd". You may also want to benchmark and see what compression level is good for you: https://wiki.tnonline.net/w/Btrfs/Zstd (benchmark tool)

            EDIT: Oh and I so do not like the '@' naming scheme so many are using!

              Sorry don't mind me, I'm just quoting your very own posts:
              Are you aware of very simple facts that most of the read workloads are random and only very small number of those workloads are sequential?
              What happens when distribution of the blocks is random and you are reading randomly? Mostly nothing .. you have ~the same level of randomness on reads.
              Nope.
              It also reduces amount of fragmentation as there is less stuff inside the block so it does not need to read as much useless data just because it is in the same blocks as the data it is looking for

              It is not at all because none of the ZFS fanbois cares about fragmentation
              fixed


              Windows has nothing to do with ZFS.

                I mean 2012, which is the same major release it also is at now, btw, while Linux has increased on any metric.

                Enough to be in bed with your mom, and make you call me daddy.

                  Can you show or describe one example of the workload under which Solaris 11.4 is slower than Linux?

                    Do you know which one year we have currently?

                      No, the EULA forbids me from doing so without Oracle's consent
                      It cuts both ways lol
