Freebsd 5.2.1 - adaptec 2200S

[Rudy Kappert]

Hello,
 
This is my first post in the freebsd-scsi mailing list, so sorry i've I
do something wrong..
 
I've freebsd 5.2.1 installed on my supermicro systeem. I use an adaptec
2200s scsi controller. But the speed of my controller with Raid-5 of
Raid-10 is very slow... 
 
Here you can see some results of bonnie: (1st = raid-5, 2nd = ide
mirroring, 3rd = raid-10)

When i look in my dmesg i get this:

Is there a problem with my harddisks? Shouldn't it be at 320MB/s,
because my adaptec should be able to use  Ultra320?
 
If you need some more informatie, please give the command to use. I'm a
little bit new in the scsi world on freebsd.
