That is still weird - But all your numbers so far are coming from bonnie. Why don't you do a test like this? (below) Write a big file to mirror. Reboot (or something) to clear cache. Now time read the file. Sometimes you'll get a different result with dd versus cat. > Could someone please send me some bonnie++ results for a 2 disk mirror or > a 2x2 disk mirror pool with sata disks? I don't have bonnie, but I have certainly confirmed mirror performance on solaris before with sata disks. I've generally done iozone, benchmarking the N-way mirror, and the stripe-of-mirrors. So I know the expectation in this case is correct. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
