In this example, a dual-core 2.4GHx “Xeon CPU E5-2676 v3” was assigned. En realidad, es un sistema de archivos virtual que contiene información del sistema en tiempo de ejecución, como la memoria del sistema, los dispositivos montados, la configuración del hardware, etc. Information displayed by the “cat /proc/cup info” command Si conoces la estructura de directorios en Linux, ya sabes que proc es un directorio especial en Linux.

Model name : Intel® Core™ i7-4710HQ CPU 2.Before doing a benchmark test, let’s check the current instance’s available memory and CPU type. You can also use grep command extract exact information: cat /proc/cpuinfo. cat /proc/cpuinfo and look for the physical address size. You can easily find this information by visiting /proc/cpuinfo file.
