Actually it is possible... You said, when only one component is
connected performance is fine.
You can try something like this:

	# gmirror remove gm0 ad2
	# swapoff /dev/mirror/gm0s1b (if you have one)

and then run this script:
#!/bin/sh
dd if=/dev/zero of=/dev/ad2s1b bs=1m count=1000 &
dd if=/dev/zero of=/dev/mirror/gm0s1b bs=1m count=1000 &
wait
