Hello, It would appear that the new sysctls for ZFS (vfs.zfs.arc_max/min) are not "taking". i.e., # cat /boot/loader.conf vfs.zfs.arc_max=134217728 vfs.zfs.arc_min=134217728 # sysctl -a | grep vfs.zfs.arc vfs.zfs.arc_max: 67108864 vfs.zfs.arc_min: 67108864 This is after a fresh cvsup run today around 10:00 CDT. -- Regards, Doug
