      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"
