Follow the below command to check the number of processor on Linux VPS.

1. Run the below command to to check exact number of virtual cpu (vCPU).

For additional information, you can display the number of cores on each CPU. Either Duo/Quad?

# cat /proc/cpuinfo |grep cpu\ cores |uniq
cpu cores       : 4
