PHP runs the .php file code and sends the result to Apache, which then sends it to the visitor. PHP frameworks are the most fastest as they work on the server side application aspects which are more reliable and more efficient in terms of speed and flexibility.
NodeJs is really fast application builder as it could manage many requests simultaneously and can easily perform one action at a time and run on a single processor, It is due to the event-orientated nature of Node.js. Apps that use Node never sit around doing nothing. As soon as there is an action that takes a little too long, the program hands over to Node.js, which will carry out other actions while waiting for the event to happen to tell it that the operation is finished.
To create fastest web or mobile applications among frameworks, NodeJs is best preferred by developers as it is easy to maintain and flexible. When we talk about the fast running application, Node is best preferable as it also inherit its features to nodeJs as expressJs is a framework of NodeJs.
