CPU, or Central Processing Unit, is that element of a personal computer or a server that runs all of the calculations. Each and every CPU runs at a certain speed and the larger it is, the speedier everything shall be processed, so in case you host resource-demanding web programs on a web server, for example, an effective processor shall allow them to be carried out faster, which will tremendously contribute to the whole user experience. The modern generations of CPUs have two and more cores, each operating at a specific speed to ensure a superior and faster performance. This type of architecture enables the processor to control various processes at one time or a number of cores to manage 1 process if it needs extra computing power to be carried out. Obviously, other variables like the amount of RAM or the connection a certain hosting server uses could also affect the efficiency of the web sites hosted on it.
