Actually, maybe that is right. Since the users are connecting via CIFS and NFS and ssh to use a ZFS volume, it stands to reason that ZFS is ultimately the thing which is performing all the read/write operations on the physical disks, right? So if I use iostat, and I see coalesced data ... I get statistics on ops and size ... which is truly the real world usage scenario for my system, right? Thus, when I am trying to optimize my disk configuration, benchmarking with iozone or whatever, those statistics will be the best measurement for me to use, when I tell iozone the blocksize it should test. Right? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
