It looks fine, in fact if that is your setup, then you are not using the multi file stuff. Your job files basically creates a process per device, which should work fine as-is. You can try and play with the iodepth batching control, iodepth_batch and iodepth_batch_complete. They both default to 1, meaning that it'll submit and complete 1 command at the time. -- Jens Axboe -- 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
