    Phoronix: FUSE Gets I/O Performance Improvements

    The FUSE module, which allows for file-systems to be run from user-space, can now process direct I/O a-synchronously. This a-synchronous direct I/O can lead to very noticeable performance improvements for FUSE-based file-systems like ZFS...

    That's not enough.

    FUSE absolutely sucks when your IO chunk is less than a few megabytes - and even if you read/write data using large/continuous chunks of data, CPU usage is just inexcusable.

      Please, Michael, "asynchronous" is not spelt with a hyphen.

      (and for Americans, "spelt" is the Commonwealth spelling of "spelled")

        INEXCUSABLE! What a GREAT word! You say there is NO EXCUSE! Not spending tons of development time for dubious results is NO EXCUSE? REALLY?

        Since there is NO EXCUSE, not even YOUR inability to fix it is an excuse! WHAT ARE YOU WAITING FOR? GET ON IT! NO EXCUSES!

        Because everything that isn't 100% efficient is totally useless?

        Even though every other alternative is a tremendous pain in the butt? Really human brain cycles are free while computer cycles are most costly?

        Because you have SO MANY important things happening on your computer all at once and they can't be disrupted by anything else?

          It's also a hot breakfast cereal, good with maple syrup

            Pro tip: you can use
            HTML Code:
            [i]text[/i]
            to emphasise your text without resorting to all caps.

              I read a news here on Phoronix about a Linux distro that used Zfs without fuse, just with an external kernel module (so it doesn't violate the CDDL/GPL licenses). It would be a good way to use it. Fuse, despite this improvements, is really slow when fs are used "seriously".

                I'm pretty sure it taints the kernel once you load it, and can't be distributed pre-linked.

                You personally can use it without violating the licences, and distribute either the module or kernel seperately and be okay, but you can't distribute the result of mixing the two.

                  More accurately, it's a variety of wheat used in that breakfast...
