For small random I/O operations I would expect a substantial performance penalty for ZFS. The reason is that RAID-Z is more akin to RAID-3 than RAID-5; each read and write operation touches all of the drives. RAID-5 allows multiple I/O operations to proceed in parallel since each read and write operation touches only 2 drives.
As always, benchmarking the application is best. :-) This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
