I take it that you're running freebsd on the "bare metal" in your 4CPU 
and 1CPU tests, and running WinXP on the bare metal in the vbox test? 
If so, are you using ATA disks and the ATA driver for all instances
of FreeBSD?  If so, then the lack of NCQ in the FreeBSD ATA driver would
explain the HDD test result.  I see similar results with VMWare.
