CPU, or Central Processing Unit, is that element of a home PC or a server that runs all the calculations. Every CPU operates at a certain speed and the larger it is, the speedier everything will be processed, so when you host resource-demanding web programs on a server, for instance, a quick processor shall allow them to be performed much faster, which will drastically contribute to the overall user experience. The current generations of CPUs have 2 and more cores, each one working at a certain speed to ensure a superior and faster performance. Such architecture allows the processor to manage different processes simultaneously or several cores to control a single process if it needs additional computing power to be completed. Needless to say, other elements such as the amount of RAM or the connection a particular server uses may also affect the performance of the websites hosted on it.
