# Code Savings Guide for Matter Applications

*   Remove unnecessary clusters from the zap configuration. Example applications have clusters enabled to support both Thread and WiFi transport layers such as the Diagnostics clusters. 

*   Remove optional features in Matter that may not be needed for a certain application. In the EFR32 build [script](https://github.com/SiliconLabs/matter/blob/latest/scripts/examples/gn_build_example.sh), there are additional build arguments that are added to either add or remove optional Matter features. For example, added a build argument disable_lcd=true will save flash by disabling the lcd screen.
