+title: 🟠 Big Signal Performance
+description: Challenge 53 is about performance while using big signal object
+author: thomas-laforge
+contributors:
+  - tomalaforge
+challengeNumber: 53
+command: signal-big-signal-performance

+
+## Information
+
+In this challenge, you can imagine a big application where you store your user state inside a service and you use this service to use your user anywhere in your application.
+The issue is when you update one property of your user, the entire application is updating.
+
+I added the `CDFlashingDirective` to vizualise when one component is rerendering.
+
+## Statement
+
+With Signal, you can now be more fine-grained in what the UI is rerendering. The goal of this challenge is to understand why everything is rerendering and you refactor the application to be more performante.
