The /etc/periodic/daily/450.status-security can take over a noisy HD thrashing hour to finish, the culprit being the find that crawls the filesystem. I was doing, too. I believe zfs requires 4+ GB RAM and 4+ CPUs (or cores) and 1+ TB of storage space to be useful. AM> I'm hoping there is some I'm not sure if there if some simple zfs tuning I need to do to improve the performance on this. I'm looking for what others use for their ZFS settings. But SGI's XFS requires nothing like that, although it is not fully supported on FreeBSD but on those systems it is being designed fpr it requires no tuning for the performance of the any kind of acceptance. I think UFS is still a rather choice for many old machines for which FreeBSD is a competent option for. 73!
