Slow loading of my FloorPlan

Hello, community! I’m currently facing an issue with slow loading time when stacking two floorplans using a vertical stack in the same YAML file for display on my 24-inch tablet. Could you please provide me with some advice or suggestions on how to improve the loading speed? Thank you!

Could we see the yaml?

kiosk_mode:
  entity_settings:
    - entity:
        input_boolean.50: "on"

                cache: false
              stylesheet: /local/floorplan.css
              rules:
                - entities:
                    - entity: input_boolean.1
                      element: areambrlight

sure @Stiltjack. Please refer to my code below. i remove my entities for easier understanding.

How long does it take to load? How big are your SVGs? Are you using the cache: true options? Have you used the devtools in your browser to see what actual file is taking a long time to load?
