        Hello,

I got a HP Proliant ML110 G4 running a NetBSD/amd64 4.99.69 GENERIC kernel.
I've recently added two Seagate Barracuda ES.2 SATA harddisk. They work
fine but the filesystem performance is very poor. In the table below
"wd0" is an older Seagate FB160C4081 harddisk, "wd1" and "wd2"
are the new harddisks:

        dd read(*)      dd write(**)    tar(***)
wd0      74MB/sec       -                4:11min
wd1     104MB/sec       102MB/sec       14:22min
wd2     108MB/sec       102MB/sec       14:06min

dd_read:        dd if=/dev/rwd<n>d of=/dev/null bs=1m count=2048
dd_write:       dd if=/dev/zero of=/dev/rwd<n>d bs=1m count=2048
tar:            Extracting the NetBSD 4.0 source tar archives to an empty
                filesystem with a size of 9 to 10GB. The tar archives are
                located on a tmpfs filesystem.

Can anybody explain why "wd1" and "wd2" are so slow? I've used "dkctl"
to make sure that the write-cache is enabled on all harddisks.

Here is the "dmesg" output of the system:

        Kind regards

P.S. I've already tried to disable "uhci" to avoid the shared interrupt
     with "piixide1". But it didn't help.
