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
