The performance of any site depends not only on the script which it functions with, but also on the server where it is accommodated. In case the hardware is powerful and reliable, the applications running on it will function well. More RAM, for example, indicates that more processes can run simultaneously, while a quicker processor means that these processes will be executed much faster. This matters since an internet hosting service includes e-mail messages, databases, logs, and so on, so each of the abovementioned processes requires some system resources to function properly. In the event that the server doesn't have a sufficient amount of power, the websites hosted on it will not perform well or can even time out in case the machine cannot manage all the requests to it. Hosting your websites on servers with suitable hardware will provide you with the performance which you would like to have for them.
