+===== Memory Tweak =====
+Per default ZFS uses as much memory as available for its ARC cache. It should not be less than 512MB and a good value is 1/4 of available memory. This property can only be set during module loading, to restrict how much memory should be used to 512MB:
+   # echo "options zfs zfs_arc_max=512M" >> /etc/modprobe.d/zfs.conf
