Default slow io from hdd

I just went from 4.0->4.5 with a completly reinstalled machine. I tossed all old idedrives and inserted 1 new satadrive (the 1.5tb seagate) otherwise its completly the same hardware. I have picked it into pieces and cleaned out all the dust.
The problem is slow transfers and high load.
Copying from one drive to another is at best 20mb/s but more common 5-10 and sometimes even dropping to 1mb/s and all this at 40-60% load?
Old system was almost constantly 20-40mb/s.
Going to test some benchmarkprograms(welcome to recommend one) tomorro, but for now i was hoping for some directions from you experts!

dmesg:

Interrupt routing issues always concern me.. boot into the UKC and disable apm, this will force the system to use acpi instead.

I have a similar system, look in the BIOS for an option to enable APIC instead of PIC, and if you see any options related to "Plug and Play OS, PnP OS", set that to "No/False".

Good luck, post the updated dmesg.. we like them.

Your hardware has both ACPI and APM. OpenBSD selected the latter. Try using ACPI instead.

At the boot> prompt, respond "-c"
At the first UKC> prompt, respond "disable apm"
At the next UKC> prompt, respond "quit"

Inspect the new dmesg, and see if the interrupt routing problem goes away.
If it does, then make this change to your kernel permanent with config(8).

As usual, great minds think alike; BSDfan was faster.
