I'm not aware of any hacks to disable APs through loader.conf. If you're
trying to benchmark the system's performance with 1 vs N CPUs, you're best
off pulling all but the BSP CPU out of the machine. For such a benchmark
to be accurate, you shouldn't make any software changes (kernel, daemons
or startup configs).
