Check CPU Speed in FreeBSD
Type the command at a shell prompt:
|
1 |
sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu' |
Sample output:
|
1 2 3 4 |
hw.machine: amd64 hw.model: Intel(R) Xeon(R) CPU X3220 @ 2.40GHz hw.ncpu: 4 hw.machine_arch: amd64 |
So I’ve Intel Xeon quad core processor running at 2.40GHz speed.
You need to use following commands in association with grep command.
FreeBSD CPUINFO using dmesg command

CPU: Dual Core AMD Opteron(tm) Processor 170 (1999.08-MHz 686-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu0: on acpi0
acpi_throttle0: on cpu0
cpu1: on acpi0
acpi_throttle1: on cpu1
SMP: AP CPU #1 Launched!
You can also dump more information using sysctl command
