Hi,
I'm currently setting up a HP ProLiant DL360 G5 with NetBSD/amd64 8.0RC2.
It has 16GB RAM...

...and two 550 GB SAS RAID-1 disks, configured via the BIOS and appearing
as a single SCSI disk:

ciss0: interrupting at ioapic0 pin 16

sd0: async, 8-bit transfers, tagged queueing
I'm wondering about the extremely slow disk performance while extracting
several pkgsrc archives. Especially the boost-jam (40 minutes) and
boost-headers (35 minutes) archives take annoyingly long.
The system is still in a freshly installed state with only default services
running. The load is constantly 1.00 while extracting, but I don't see
where the processing power is lost. bzcat and tar only use around 8%.

No interrupt storm either:

Anybody knows why the disk operations on this servers are so slow?
What can I check?
