ZFS, atime=off, SW RAID-Z 6 disks, snv_44 > 133MB/s Well, the UFS results are miserable, but the ZFS results aren't good - I'd expect between 250-350MB/s from a 6-disk RAID5 with read() blocksize from 8kb to 32kb. Most of my ZFS experiments have been with RAID10, but there were some massive improvements to seq I/O with the fixes I mentioned - I'd expect that this shows that they aren't in snv44. - Luke _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
