CPU Core Auslastung anzeigen
Um die aktuelle Auslastung der einzelnen CPU Cores anzuzeigen helfen diverse Tools wie top oder systat:$ top -P

CPU Modell / Geschwindigkeit unter FreeBSD anzeigen
Um unter FreeBSD zu sehen welche CPU verbaut ist, kannst Du einfach folgenden Befehl verwenden:# sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu|hw.clockrate'Der Output sieht dann z.B. so aus:
hw.machine: amd64 hw.model: Intel(R) Atom(TM) CPU D510 @ 1.66GHz hw.ncpu: 4 hw.machine_arch: amd64 hw.clockrate: 1673Mit dmesg erhält man ebenfalls die gewünschten Informationen:
# grep -i cpu /var/run/dmesg.bootDer Output sieht dann auf diesem Server so aus:
CPU: Intel(R) Atom(TM) CPU D510 @ 1.66GHz (1673.34-MHz K8-class CPU) FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP/HT): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP/HT): APIC ID: 3 cpu0: <ACPI CPU> on acpi0 cpu1: <ACPI CPU> on acpi0 cpu2: <ACPI CPU> on acpi0 cpu3: <ACPI CPU> on acpi0 p4tcc0: <CPU Frequency Thermal Control> on cpu0 p4tcc1: <CPU Frequency Thermal Control> on cpu1 p4tcc2: <CPU Frequency Thermal Control> on cpu2 p4tcc3: <CPU Frequency Thermal Control> on cpu3 SMP: AP CPU #1 Launched!
