I have a Supermicro with the C7X58 motherboard and an i7 930 cpu, and it is nowhere near the performance it should be. A buildworld just took 22.5 hours! bryce@tahiti[~]>uname -a FreeBSD tahiti.bryce.net 8.1-STABLE FreeBSD 8.1-STABLE #0: Tue Sep 7 22:45:38 CDT 2010 root@tahiti.bryce.net:/usr/obj/usr/src/sys/GENERIC amd64 I have disabled "Legacy USB Support" 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 (currently a zfs mirror), so it is not likely to be an hdd 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. 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! ::Bryce::
