The performance of any kind of Internet site depends not only on the script which it uses, but also on the server where it is accommodated. When the hardware is powerful and reliable, the applications that run on it will function well. More RAM, for example, indicates that more processes can run concurrently, while a quicker processor indicates that all these processes will be executed faster. This matters because an internet hosting service involves e-mails, databases, logs, and so on, so each of the last mentioned processes requires some resources so that it can work efficiently. If the server does not have a sufficient amount of power, the Internet sites hosted on it will not perform well or can even time out in case the machine is unable to handle all the requests to it. Hosting your sites on servers with adequate hardware will provide you with the performance which you would like to have for them.
