P45 Gigabyte EP45-DS3P. I put the AOC card into a PCI slotI'm not sure how many "half your disks" are or how your vdevs are configured, but the ICH10 has 6 sata ports at 300MB and one PCI port at 266MB (that's also shared with the IT8213 IDE chip) so in an ideal world your scrub bandwidth would be 300*6 MB with 6 disks on ICH10, in a strip 300*1 MB with 6 disks on ICH10, in a raidz 300*3+(266/3) MB with 3 disks on ICH10, and 3 on shared PCI in a strip 266/3 MB with 3 disks on ICH10, and 3 on shared PCI in a raidz 266/6 MB with 6 disks on shared PCI in a stripe 266/6 MB with 6 disks on shared PCI in a raidz we know disk don't go that fast anyway, but going from a 8h to 15h scrub is very reasonable depending on vdev config.

Agreed, sounds like you're saturating the PCI port. I'm pretty sure that when Thumper uses that board, they have 6 of them in PCI-X slots, which of course wouldn't have the same bandwidth limitation. --eric -- Eric D.
