The quality of the web hosting service that you will receive for your sites depends not only on the features that a given plan has, but also on the hardware your web applications work on. Increased CPU speeds, for instance, indicate that the processes running on the server will be carried out faster, while additional physical memory (RAM) indicates that more processes can run at once. The grade of the hardware may also impact the general performance and reliability of the server. As the web hosting service today includes not just file storage, but also databases, e-mails, logs, and many others, more processing power is necessary to run all of the system processes and to ensure that they function correctly and without lag. In the event that the hardware is not powerful enough, the result will be slower websites and / or even service timeouts since the machine might not be able to manage all requests to the sites hosted on it.
