I have a system (obsd3.8/sparc64) with 2 identical scsi drives (4 partitions + 1 swap each). The largest partition (10G) is mirrored over the 2 drives as a ccd with interleave factor 16.
And 1.2M/s is rather less that what I'd have expected, is this figure really the disk transfer rate?
my personal experience is that 16 is way too small. spend a few hours benchmarking at increasing interleaves, and then make your decision. for a 2 scsi disk system i ended up with an interleave of 312, judged on the basis of bonnie benchmarking, wich lets you trade off raw speed, small writes and cpu load.
