> P45 Gigabyte EP45-DS3P. I put the AOC card into a PCI slot
I'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.
