Pawel are there tests that can help? also how can we determine the real memory consumption by zfs,arc and his vfs cache share ? how can we precisely instrument zfs ? i am experiencing very high memory usage on all of my four boxes with zfs, some eventually panic or lockup on higher load patterns because of this. disabling zfs bring them to normal behaviour. thanks for all our work on bringing zfs to FreeBSD Pawel, zfs is really nice! __________________________________________________ Do You Yahoo!?
