Another suggestion might be to load tabs lazily. I don't think FXML "pre-loading" is possible.

On a 13900K CPU, show() method requires more than 750ms, this feels laggy... After the first show() call, loading the tab pane is much faster... Is there a way to "preload" an fxml? I tried to show() and hide() it immediately and it seems to help, but what is the best way to do it? Thanks Davide
