    I don't understand, filesystem formats are really just a layout of bits on a medium. The filesystem itself doesn't have any performance, it's just a layout.
    Actually, a badly designed filesystem (i.e. the bits layout) can "have" bad performance if it makes difficult or impossible to write an efficient implementation.

    Yes it does: as you say, the implementation is where performance is measured. If you test ntfs-3g on linux you have no idea of the performance of the windows driver because they are different implementations; you have no way of testing the actual ntfs windows driver on linux. And the OS probably matters because the driver might use kernel code, and the OS userspace calls the driver; so even the same driver could perform very differently in different OSes (because the OS userspace is using it right/wrong, or because kernel code the driver is calling is faster/slower).

    Since we are talking about measuring the performance of the ubuntu on windows layer, a good test would be to compare ubuntu on windows with plain windows. Ubuntu on Windows (I believe) uses the windows ntfs driver; so if windows is faster than ubuntu, probably that means that the conversion layer is not so efficient (but it could still be that linux applications optimize system calls to be fast on an ext4 filesystem, though that's less likely).

      I hope Microsoft decide to provide some sort of native Wayland compatibility layer rather than X11. And if Apple did something like that too a then it would mean Linux user space could be a better universal platform than Windows or OSX.

        so in the end starting the wine project was a good move, so good that microsoft copied it

        probably the linux ecosystem is grown to a point that it is a good source of applications even for windows

          so... where is the so much famed linux superiority in resources overhead? Where did all that talk about so many windows service running into the background that will slow down your onw performance?... i'm disappointed. I do really believe in linux, but sometimes the difference is just not there.

            Thats it. No software package manager and proud of it. These package manager are often despised by those, who come from the windows world.

            Recently, windows got one. It is called "Storage Spaces".

              Hi,

              Would it be possible to have an update of this benchmark ?

              About the file system low result's, is there a method to improve it in bash on windows ?

              Regards,
              Frédéric

                Phoronix Premium readers already know, but new benchmarks of it coming on Thursday.

                  Hi,

                  To reply to myself

                  This Creative upgrade of Windows, bash on windows moved from ubuntu 14.04 to the ubuntu 16.04, but there is no improvement on the file system benchmark


                  The benchmark filesystem, need to be done in the external folder than bash, the result seems better.
                  https://superuser.com/questions/1114...windows-drives -> /mnt/d

                  And also I tried to create a workspace in the $HOME but as if you try to create a file with windows explorer or other windows apps, in the "bash" you can't access to them.
                  https://github.com/Microsoft/BashOnWindows/issues/45
                  => confirmed that when using mklink /J to create a windows link to the Lxss/rootfs path, files could be updated but newly created files weren't visible in WSL.


                  to share file edition/creation between windows and bash , it advices to use external folder.
