Hi Matt. I ran your suggested tests on this today. And from the looks of it, all seems fine. The performance on this driver is almost half of what I get on the Adaptec 7xxx driver, but I'll take it considering all the other RAID1 overhead. Even though I've seen better speeds on these. Just to make sure it wasn't the box, I did a test on a similar box and got the same results. Anyway you can see below where it started reading and it seemed to go though just fine with no lag, etc. Device 1K-blocks Used Avail Capacity Type /dev/amrd0s1b 524160 0 524160 0% Interleaved dd if=/dev/amrd0s1b of=/dev/null bs=32k tin tout KB/t tps MB/s us ni sy in id 0 64 0.00 0 0.00 1 0 2 0 97 0 21 0.00 0 0.00 1 0 3 0 95 0 21 0.00 0 0.00 0 0 1 0 99 0 21 0.00 0 0.00 0 0 0 0 99 3 43 0.00 0 0.00 0 0 1 0 99 27 30 0.00 0 0.00 0 0 0 0100 3 87 7.50 4 0.03 0 0 0 0 99 2 107 0.00 0 0.00 0 0 1 0 99 1 62 0.00 0 0.00 0 0 0 1 98 1 82 0.00 0 0.00 0 0 1 0 99 1 62 0.00 0 0.00 0 0 1 0 99 0 21 4.00 8 0.03 0 0 2 0 98 0 22 32.00 615 19.21 1 0 3 0 96 0 21 32.00 787 24.60 0 0 1 1 98 0 21 32.00 785 24.53 0 0 2 1 97 0 21 32.00 790 24.69 0 0 2 1 97 0 21 32.00 786 24.57 0 0 1 0 99 0 21 32.00 688 21.50 0 0 3 0 96 0 21 32.00 782 24.45 1 0 3 0 96 0 21 32.00 788 24.63 1 0 4 0 95 tty amrd0 cpu tin tout KB/t tps MB/s us ni sy in id 0 64 32.00 784 24.50 0 0 3 1 95 0 21 32.00 699 21.85 0 0 6 1 93 0 21 31.88 787 24.50 0 0 2 1 97 0 21 32.00 788 24.63 0 0 1 0 98 0 21 32.00 784 24.50 0 0 2 0 98 0 21 32.00 784 24.50 0 0 2 1 98 0 21 32.00 770 24.07 0 0 2 0 98 0 21 32.00 789 24.66 0 0 1 0 99 0 21 32.00 785 24.53 0 0 2 1 97 0 21 32.00 774 24.19 0 0 1 1 98 0 21 32.00 786 24.57 0 0 1 0 98 0 21 31.88 788 24.53 0 0 2 1 97 0 21 32.00 788 24.63 0 0 2 0 98 0 81 32.00 100 3.12 0 0 1 0 99 0 21 7.50 4 0.03 0 0 2 0 98 0 21 0.00 0 0.00 0 0 1 1 98 0 21 0.00 0 0.00 0 0 0 0100 0 21 0.00 0 0.00 0 0 2 0 98 0 21 0.00 0 0.00 0 0 0 0 99 0 21 0.00 0 0.00 0 0 2 0 98 16384+0 records in 16384+0 records out 536870912 bytes transferred in 21.134953 secs (25402040 bytes/sec) -- Robert Blayzor, BOFH INOC, LLC rblayzor@inoc.net "I don't need parents.
