Improve ZFS Performance



  • Just something I ran across don't know if this will work on pfsense 2, can some one test

    Improve ZFS Performance:

    Tweaking the Boot Loader
    ZFS will not work smoothly without tweaking the system parameters.
    You can tweak your boot loader (/boot/loader.conf) using the following parameters:

    #Your Total Physical Memory minus 1 GB
    vm.kmem_size="3g"
    vm.kmem_size_max="3g"

    #512MB should be fine.
    vfs.zfs.arc_min="512m"

    #Your Physical Memory minus 2GB
    vfs.zfs.arc_max="2048m"

    #Set the following to 1
    vfs.zfs.vdev.min_pending="1"
    vfs.zfs.vdev.max_pending="1"
