+# Reducing Layout Complexity
+
+## Background information
+
+Complex layouts can slow down WPF performance, especially with nested controls or excessive use of `Grid` and `StackPanel`.
+
+## Avoid Nested Grids and StackPanels
+
+Overuse of nested layouts can create rendering bottlenecks. Try to simplify the structure or use a `UniformGrid` or `DockPanel` for simpler arrangements.
+
+```xaml
+<!-- Instead of nesting multiple StackPanels, use a single DockPanel -->
+<DockPanel>
+    <TextBlock Text="Header" DockPanel.Dock="Top" />
+    <ListView DockPanel.Dock="Bottom" />
+</DockPanel>
+```
+
+## Prefer Static Resources Over Dynamic Resources
+
+Static resources are faster to load compared to dynamic ones. Use dynamic resources only if you need runtime changes in resource values.
+
+```xaml
+<!-- Use StaticResource instead of DynamicResource for better performance -->
+<Style x:Key="ButtonStyle" TargetType="Button" BasedOn="{StaticResource BaseButtonStyle}" />
+```
+
+> [!NOTE]
+> Dynamic resources are reevaluated each time they’re used, which may impact performance.
