CPU, or Central Processing Unit, is that component of a computer system or a server which performs the calculations. Every CPU functions at a particular speed and the bigger it is, the faster everything shall be processed, so when you host resource-demanding web apps on a hosting server, for example, an effective processor will enable them to be executed much faster, which will significantly contribute to the entire user experience. The modern generations of CPUs have 2 and more cores, each working at a specific speed to guarantee a better and quicker performance. This type of architecture enables the processor to manage various processes at one time or a number of cores to control a single process if it requires more computing power to be completed. However, additional factors including the amount of RAM or the connection that a given hosting server uses can also affect the efficiency of the web sites hosted on it.
