The performance of every Internet site depends not just on the script that it makes use of, but also on the web server where it is accommodated. In case the hardware is powerful and reliable, the applications running on it will perform well. Extra RAM, for instance, suggests that more processes can run concurrently, while a faster processor indicates that all these processes will be executed more quickly. This matters because a web hosting service includes email messages, databases, logs, and so on, so each of the abovementioned processes must have some resources so that it can work properly. If the server does not have enough power, the sites hosted on it won't perform well or may even time out in case the machine is unable to manage all the requests to it. Hosting your websites on servers with suitable hardware will give you the performance that you want for them.
