The kvm port was never finished so you are most likely using jit which is slow. If you are looking for reasonably fast x86-on-x86 virtualization you are better off using emulators/virtualbox-ose: https://wiki.freebsd.org/VirtualBox HTH, Juergen PS: Or bhyve but that so far is only in -current and can't run other guests than FreeBSD yet: http://bhyve.org/
