Ubuntu / Centos - Linux - Check Hyperthreading is enabled or not

Check Hyperthreading status :

Run command :
cat /proc/cpuinfo

If the number of siblings is equal to the number of cores then you have CPUs which are not hyperthreading or hyperthreading is switched off, If the number of siblings is 2x the number of cores then you have a hyperthreading CPU with hyperthreading switched on.
