I don't seem to have the last 2 you've asked about. 'sysctl -a | egrep "clockrate|cpu"' reported the following: kern.clockrate: { hz = 100, tick = 10000, profhz = 1024, stathz = 128 } kern.threads.virtual_cpu: 1 kern.ccpu: 1948 kern.smp.maxcpus: 1 kern.smp.cpus: 1 hw.ncpu: 1 hw.clockrate: 1794 hw.acpi.cpu.cx_supported: C1/0 hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu.cx_usage: 100.00% machdep.cpu_idle_hlt: 1 dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=\_PR_.CPU0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 1796 dev.cpu.0.freq_levels: 1796/-1 1571/-1 1347/-1 1122/-1 898/-1 673/-1 449/-1 224/-1 dev.acpi_throttle.0.%parent: cpu0 dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%parent: cpu0
