root@rock:/root sysctl -a | grep speed
hw.fwmem.speed = 2
hw.sbp.max_speed = -1
root@rock:/root sysctl -a | grep mach
hw.machine = amd64
hw.machine_arch = x86_64
machdep.booted_kernel = netbsd
machdep.diskinfo: 80:156301488(1023/255/63),2 81:156301488(1023/255/63),2 wd0:80,81 wd1:80,81
machdep.sleep_state = 0
machdep.powernow.frequency.target = 2200
machdep.powernow.frequency.current = 2200
machdep.powernow.frequency.available = 1000 1800 2000 2200
seems to be at full speed, not much google on
hw.sbp.max_speed or hw.sbp.

well it seems sync is queueing a lot of stuff and
tieing up the cpu getting it to the drive.
