— In the case the component state is being being restored

— 

I mean that whatever changes I made in component A when on url "/test1", all the changes are being restored in url "/test2"

— I’ve just tested, and apparently yes, this is a normal behavior, you don’t want it?

— You could wrap the component like: const B = props => <A {...props} />

— Or you could do something like:

<Route path="/route1" render={(props) => <A key="route1" {...props}></A>} />
<Route path="/route2" render={(props) => <A key="route2" {...props}></A>}/>

— There are a variety of options, and all of them can be good in certain situations.
In general you want to keep a page very fast and responsive.
Loading a page by parts can be good if those parts are not necessary and are very heavy.
