# Improving model performance

What to do when your model reaches the performance threshold

When Rayon shows that your model has passed the **80% performance threshold**, it means the file is becoming heavy and may start to feel slower.

The core idea is simple: **the more content Rayon needs to display and manage at once, the heavier the model becomes.**

To improve performance:

* **Hide heavy layers** — if a layer contains a lot of geometry and you do not need it right now, hide it.
* **Remove unnecessary content** — delete unused geometry, old iterations, overly detailed imports, or large images.
* **Split into multiple canvases** — separate floors, drawing types, or areas that do not need to be edited together.
* **Split into multiple models** — for very large projects, divide the project into separate Rayon files.
* **Use Xrefs** — reference supporting drawings instead of duplicating their geometry inside your active model.

A good rule of thumb: **keep visible only what you need for the work you are doing.**
