I agree with that too. I'm fine with the patch, I'm just a bit worried about the batch_request vs nr_requests ratio. Are you sure 1/4 is always a good ratio? In my previous testing, a batch value of more than 32 had little impact and usually changed things for the worse. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
