+```rust
+pub struct ComponentPerformanceMetrics {
+    pub component_name: String,
+    pub render_times: Vec<Duration>,
+    pub memory_usage: Vec<u64>,
+    pub performance_score: f64,
+    pub meets_targets: bool,
+}
+```
+
+#### `OptimizationRecommendation`
+```rust
+pub struct OptimizationRecommendation {
+    pub title: String,
+    pub description: String,
+    pub category: OptimizationCategory,
+    pub priority: OptimizationPriority,
+    pub estimated_effort_hours: f64,
+    pub expected_impact_percent: f64,
+    pub roi_score: f64,

+```
+
+## 🔧 Configuration
+
+### Performance Targets
+Default performance targets can be customized:
+
+```rust
+pub struct PerformanceConfig {
+    pub max_component_size_kb: f64,      // Default: 5.0 KB
+    pub max_render_time_ms: f64,         // Default: 16.0 ms
+    pub max_memory_usage_mb: f64,        // Default: 1.0 MB
+    pub monitoring_enabled: bool,        // Default: true
+}
+```
+
+### Custom Configuration
+```bash
+# Custom performance targets
+performance-audit audit \
+  --max-component-size-kb 3.0 \
+  --max-render-time-ms 12.0 \
+  --max-memory-usage-mb 0.8
+```
