I can't provide you "reliable" or "authoritative" guidelines, but I have an advice which seems to work. On amd64 set your vm.kmem_size to at least the amount of available memory that you got, or even more (1.5x, 2x). An easy way to do that (1x) is to set vm.kmem_size_scale="1". In head this is already done automatically, MFC to stable/8 is expected. As to arc_max/arc_min, set them based your needs according to general ZFS recommendations. -- Andriy Gapon _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
