Serious speed problems using Local by FlyWheel

I have serious speed problems using Local by FlyWheel.
Pages (frontend) take approximately 16s to load, backend is even larger. Working on the creation of a custom theme with this delay is completely unbearable.
Is this speed normal when using Local by FlyWheel?
How can I improve this?

If you are using Local on a Mac, read my post:

No, I use Win10 :frowning:

Do you have any reading for it?
