The hardware setup of the server where you host your Internet sites is rather important and can influence their performance. As a site includes also databases, logs, a Control Panel to handle the content, an e-mail service, and many others, you need appropriate hardware which will support all of these processes. A machine with a high CPU speed suggests that your web applications will be executed quicker, while extra physical memory will enable more system processes to run at the same time, so the hardware shall have direct impact on how your Internet sites perform and if the server is not powerful enough, they will work slowly or will not work at all. In this light, you should check not just what functions a certain hosting plan includes, but also if the hardware will be adequate to support these capabilities.
