Changing slide at export HTML5

Problem: When I click a button to go to another slide, it takes 1 or 2 seconds to change of slide (even locally or in server). Is there a way to change the slide instantly? Additional, in some projects when happens the change of slide it shows a white background for about 1 second (the correct background of slide contains an image).
