    100% usage on block devices:

    Note atime and compression are both disabled on this ZFS dataset.

  3. gmaxwell commented at 9:09 PM on June 10, 2012: contributor

    If you want to keep a powerful machine powerful, do not use a userspace filesystem. (I assume thats how you're using ZFS on Fedora 17, because it certainly isn't part of Fedora)

  4. Rudd-O commented at 9:11 PM on June 10, 2012: none

    Who told you that I was using an userspace filesystem?

    I am not:

    Is this still a problem?

  6. Diapolo commented at 6:14 AM on June 11, 2013: none

    With 0.6.2 sure ^^, with current versions it should be much smoother...

  7. Rudd-O commented at 1:21 AM on July 1, 2013: none

    Current versions are buttery smooth. I checked with the old machine. The new machine does 20GB/s from RAM to CPU and 320 MB/s from the SSD, so I have no problem anymore.

    But the more optimized the better. Bitcoin should not be a expensive computer boys' club.

    @Rudd-O If this is no longer an issue feel free to close it.
