I've found that using 12 stripes on 8 paths had some times slower performance than 4 stripes (greatest common denominator of disks and i/o paths). Depended on the type of writes being done and was also very inconsistent. 4 stripes acted predictably, 12 would give me good and bad performance inconsistently. As a result, I always use the greatest common denominator. -- Brandon S.
