Have you had some discussions with people who have a good understanding of the kernel I/O scheduler about looking at this work load as an optimization target? Also, thinking worse case scenario. If in the rawhide runup if the release management team find the disk I/O scheduling is a significant problem when many of our default services "go native." Would it be a reasonable fallback to flip back some of the services to sysinit style scripts by default? I'm not suggesting it will be a significant problem (nor am I putting my neck out and defining what significant means here...) but its good to have an understanding of where rough edges are anticipated and to have a fallback plan if the kernel scheduling can't get fixed in the pre F14 time scale. -jef -jef -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
