Thanks Chris & Jens. Sounds really obviously now - just run multiple threads of FIO. This is what I get now on 512B block size: 203,216 IOPs That is using 8 threads and an IOdepth of 32. The RAID array is now being stressed and not the CPU. -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
