I hate to see something like this go ahead based on empirical results without theory. It might make things worse somewhere else. Do you have an explanation for why the IO chunks are larger? Is the I/O scheduler not building large I/Os out of small requests? Is the queue running dry while the device is actually busy? -- Bryan Henderson San Jose California IBM Almaden Research Center Filesystems - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
