RequestScoped managedbean created every changes in the view?

I have a question about RequestScoped ManagedBean :

It seems like the RequestScoped ManagedBean is created every time we change something in the view, indeed, if we change value of <p:selectOneMenu>, for example, method declared as @PostConstruct is called.

I think this will slow the application.

Can some explain more this issue ?

RequestScoped ManagedBean will be created for every request made. If changing something in the view is going to make a new request, e.g. ajax request, then the bean will be created and its method annotated with @PostConstruct will get every time bean is created

I think this will slow the application

What kind of operation are you performing in that PostConstruct annotated method? What is it that you need everytime a request is created? If you could avoid that, then there is no need to write a PostConstruct
