Benchmark

Geekbench

Geekbench is a cross-platform benchmark that measures the performance of your computer's processor and memory.

Sysbench

sudo apt-get update
sudo apt-get install sysbench
sysbench --num-threads=1 --test=cpu --cpu-max-prime=20000 --validate run
# sysbench version is 0.4.12

sysbench --threads=1 --test=cpu --cpu-max-prime=20000 --validate run
# sysbench version 1.0.11

Note that

• The /proc/cpuinfo shows only the current CPU freq. If we specify all threads when we ran the sysbench, we will be able to see the CPU MHz changed when we run watch.

watch -n1 "cat /proc/cpuinfo | grep \"MHz\""

• To get the maximum freq, follow this

sudo cat /sys/devices/system/cpu/*/cpufreq/cpuinfo_max_freq

• for the Xeon(R) E5-1650 @ 3.2GHz,
