I have not looked at it recently but for any access greater than ~ 16K ZFS was more efficient than UFS. It's just one partial data point but the conventional wisdom that ZFS will use more cpu is not an absolute truth. Even more so for RAM, ZFS with 128K record make efficient use of metadata. The only ram it needs to operation is 10 seconds of of your workload's throughput and that can be tuned down in appliances. -r > Now it _might_ be possible for some of these characteristics to be > changed with a code re-write targeting small devices, and probably a > feature-limited zpool/zfs version number, but the effort would be > non-trivial. > > -- > Carson > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
