I have a new F12 system that is experiencing *agonizingly slow* SATA HDD performance, and I can't figure out why. No errors messages at all, just *really slow*. Mobo: GigaByte GA880GMA-UD2H Memory: 8Gbyte 1333 Disk: 1TB Western Digital CPU: AMD Phenom II X6 1090T The system performance is generally pretty decent, except when it needs to do a lot of disk I/O, in which case, it's *really slow*. I have other, much older, systems where similar operations (for example, a yum -y update) complete 5 to 8 times faster than on the "problem" system. I've noticed that if it's doing bulk disk I/O, the interactive performance of the system becomes horrible, almost like it's doing PIO to the disk and locking everything else out. I'm doing an upgrade to F13 (via preupgrade) on the system right now, and after two hours, it's only about 12% complete. I've seen *much* traffic about abyssmal SATA performance related to Ubuntu, but nothing much concrete relevant to Fedora. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
