Advices to improve performance in javafx

I'm working on an app where I need to draw a lot of data. There are different functions that can be used to work with the data. The main functions share two views, that right now I draw every time I start the functions. They differ in the middle part where the data is displayed different. Right now my main goal is to improve the performance of the app. When I switch from view A to B runs smoother than the other way around. My idea is to store all the parts (from all views) in a list so when I jump back to the view I can reuse them instead of building them again. Is this a good idea? Are there some general performance advices when building an app with javafx?

In GUI desktop development, there is a technique named "double buffering", which is useful to make fast screen flips:

It consists on having two separated and different panels that occupy the whole application viewport and that must be permanently updated, but just one of them must be visible at the same time. Changing from one to another is as fast as to hide one of them and to show the other one.
