I have a Supermicro with the C7X58 motherboard and an i7 930 cpu, and
it is nowhere near the performance it should be.

As you can see that is 22.5 hours!
I have disabled Legacy USB in the BIOS and that helped, but I'm not
finding any other setting that are getting things where they need to
be.
I have tested the two system drives independently, so it is not likely
to be a HD issue.
Here's the verbose dmesg boot details - http://www.bryce.net/files/dmesg.boot
And, the IPMI ASL in case that is of any value - http://www.bryce.net/files/tahiti.asl
Currently, I'm not running powerd, performance is not better with it
running.
Here's /boot/loader.conf:
root@tahiti[/usr/src]#cat /boot/loader.conf
ahci_load="YES"
coretemp_load="YES"
zfs_load="YES"
vfs.root.mountfrom="zfs:system"
#vfs.zfs.prefetch_disable=1
kern.maxfiles=16384
# async i/o
aio_load="YES"
# VirtualBox
#vboxdrv_load="YES"
# SMB
#ichsmb_load="YES"
#smb_load="YES"
# Power Saving
#kern.hz="100"
# Disable APIC subsystem - no longer needed when disabling lapic below
#hint.apic.0.disabled="1"
# Disable local APIC (LAPIC) timer - for C3 state
#hint.apic.0.clock="0"
# Avoid 128 interrupts/sec per core, at cost of scheduling precision
#hint.atrtc.0.clock="0"
# Disable throttle control (and rely on EIST)
hint.p4tcc.0.disabled="1"
hint.acpi_throttle.0.disabled="1"
Thanks in advance for your time!
