ML570 and HP NetRAID-3Si

Hello.
I have a first generation Compaq ML570 server with HP NetRAID-3Si controller. I have configured the arrays and lost 2/3 of tranfer rate. When the disks were connected without a raid controller, I had 50MV\s on fastest disks (10k ultra3, 18GB), about 30-40 on 10k\ultra2\3 9gb and 20-22MB\s on 9gb ultra2 7200rpm.
Now it's 15MB\s on every array - 2x18 10k in raid1, 7x9 10k in raid5 and 3x9 7,2k in raid5. I have deleted the both raid5 arrays (disk still connected to controller) and with one raid1 it's still the same - 15MB\s measured by HDTune under Windows 2003.

What can I do with it?
