Could you try with this patch please?

No IO speed difference (still 0.200 ~ 0.400 MB/s with direct IO).
The dmesg output just add new line:
da0: Command Queueing Enabled
Ok, it might have been incomplete. Can you try this patch instead?
http://leaf.dragonflybsd.org/~swildner/cam_probe2.diff
It includes the first patch, so undo the first one before applying this
one.
If that too doesn't help, can you check how many dev_openings it shows
with 'camcontrol tags da0 -v'? mintags and maxtags give the limits. If
dev_openings is 1, can you check if raising helps, which should work with
'camcontrol tags da0 -N <number>', within the limits.
