I tried to track this problem using VisualVM and found that javafx.scene.CssStyleHelper.createStyleHelper() took the most CPU time when I switched perspective A again.
Does this mean that the interface of perspective A has been redrawn?
If you switch between different parts in the same perspective, this problem will not occur.

You are right there are 2 problems:
* at some time in JDK-8 Timeframe a performance fix for CSS processing was reverted
* we detach the active perspective on switching
We can (and should) do 2 things:
* apply a workaround we already use for eg detach to minimize the impact by detaching
* don't detach the node containing the perspective but keep it in the SG

I'm back to the question. In the efx3.6 release note, I noticed that the second item had been fixed(we detach the active perspective on switching).
And I tried different versions of jdk and found that before jdk1.8_181 CSS was very good . Do you know anything about the first(CSS processing was reverted), Can I track the issue in the jdk repository.
Thank you very much for your work!
