The only tuning I did was to set vm.kmem_size to 1GB. You still need to do this very tuning even on amd64. Could you post output of: # sysctl vm.kmem_size # sysctl vm.kmem_size_max # sysctl vfs.zfs # zpool status # zpool list # zfs get all And place /var/run/dmesg.boot somewhere? --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
