Hi,

In reality, I have 4 cores:
CPU: Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz (3093.05-MHz K8-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
FreeBSD/SMP: 1 package(s) x 4 core(s)
  cpu0 (BSP): APIC ID:  0
  cpu1 (AP): APIC ID:  2
  cpu2 (AP): APIC ID:  4
  cpu3 (AP): APIC ID:  6

with sched_ule, top -H shows computer being 40.2% idle:

CPU:  0.0% user, 59.8% nice,  0.0% system,  0.0% interrupt, 40.2% idle
