+
+## Komponenten
+
+### 1. Component State Cache
+
+**Zweck**: Cached Component State zwischen Requests für schnellere Rehydration.
+
+**Performance**: ~70% schnellere Component-Initialisierung
+
+**Verwendung**:
+
+```php
+use App\Framework\LiveComponents\Cache\ComponentStateCache;
+use App\Framework\Core\ValueObjects\Duration;
+
+$cache = $container->get(ComponentStateCache::class);
+
+// State speichern
+$cache->store(
+    componentId: $componentId,
+    state: $componentState,
+    ttl: Duration::fromHours(1)
+);
+
+// State abrufen
+$cachedState = $cache->retrieve($componentId, $currentState);
+
+if ($cachedState !== null) {
+    // Cached state verwenden - ~70% schneller
+    $component->hydrateFromCache($cachedState);
+} else {
+    // Fresh initialization
+    $component->initialize($freshState);
+}
+```
+
+**Auto-TTL basierend auf Component-Typ**:
+```php
+// Auto-optimierte TTL
+$cache->storeWithAutoTTL(
+    componentId: $componentId,
+    state: $state,
+    componentType: 'counter' // 5 Minuten TTL
+);
+
+/*
+TTL-Strategien:
+- counter, timer: 5 Minuten (frequent updates)
+- chart, datatable: 30 Minuten (moderate updates)
+- card, modal, layout: 2 Stunden (static-ish)
+*/
+```
+
+### 2. Slot Content Cache
+
+**Zweck**: Cached resolved Slot-Content für wiederverwendbare Komponenten.
+
+**Performance**: ~60% schnellere Slot-Resolution
+
+**Verwendung**:
+```php
+use App\Framework\LiveComponents\Cache\SlotContentCache;
+
+$cache = $container->get(SlotContentCache::class);
+
+// Single Slot speichern
+$cache->storeResolvedContent(
+    componentId: $componentId,
+    slotName: 'header',
+    resolvedContent: $renderedHeaderHtml,
+    ttl: Duration::fromMinutes(30)
+);
+
+// Slot abrufen
+$cached = $cache->getResolvedContent($componentId, 'header');
+
+if ($cached !== null) {
+    return $cached; // ~60% schneller
+}
+```
+
+**Batch Operations für Multiple Slots**:
+```php
+// Batch store - alle Slots in einem Call
+$cache->storeBatch(
+    componentId: $componentId,
+    slots: [
+        'header' => $headerHtml,
+        'footer' => $footerHtml,
+        'sidebar' => $sidebarHtml
+    ],
+    ttl: Duration::fromHours(1)
+);
+
+// Batch retrieve
+$cachedSlots = $cache->getBatch($componentId, ['header', 'footer', 'sidebar']);
+
+if (isset($cachedSlots['header'])) {
+    // Header aus Cache
+}
+```
+
+**Content-Hash Based Invalidation**:
+```php
+// Automatische Invalidierung bei Content-Änderung
+$cache->storeWithContentHash(
+    componentId: $componentId,
+    slotName: 'dynamic-content',
+    resolvedContent: $dynamicHtml,
+    ttl: Duration::fromHours(2)
+);
+
+// Wenn Content sich ändert, ändert sich Hash → alter Cache ungültig
+```
+
+### 3. Template Fragment Cache
+
+**Zweck**: Cached gerenderte Template-Fragmente für wiederverwendbare UI-Komponenten.
+
+**Performance**: ~80% schnellere Template-Rendering
+
+**Verwendung**:
+```php
+use App\Framework\LiveComponents\Cache\TemplateFragmentCache;
+
+$cache = $container->get(TemplateFragmentCache::class);
+
+// Template Fragment speichern
+$cache->store(
+    componentType: 'card',
+    renderedHtml: $renderedCardHtml,
+    data: ['title' => 'User Profile', 'userId' => 123],
+    variant: 'default',
+    ttl: Duration::fromHours(2)
+);
+
+// Template abrufen
+$cached = $cache->get(
+    componentType: 'card',
+    data: ['title' => 'User Profile', 'userId' => 123],
+    variant: 'default'
+);
+```
+
+**Remember Pattern**:
+```php
+// Eleganter: get from cache or execute callback
+$renderedHtml = $cache->remember(
+    componentType: 'card',
+    data: $templateData,
+    callback: fn() => $this->templateRenderer->render('card.view.php', $templateData),
+    variant: 'compact',
+    ttl: Duration::fromHours(1)
+);
+```
+
+**Static Templates** (keine Data-Variationen):
+```php
+// Für Layouts, Header, Footer - komplett statisch
+$cache->storeStatic(
+    componentType: 'layout',
+    renderedHtml: $layoutShellHtml,
+    variant: 'default',
+    ttl: Duration::fromHours(24) // Lange TTL
+);
+
+$layoutHtml = $cache->getStatic('layout', 'default');
+```
+
+**Auto-TTL basierend auf Component-Typ**:
+```php
+$cache->storeWithAutoTTL(
+    componentType: 'header', // 24h TTL (static)
+    renderedHtml: $headerHtml,
+    data: $headerData,
+    variant: 'default'
+);
+```
+
+### 4. Cache Invalidation Strategy
+
+**Zweck**: Koordinierte Cache-Invalidierung über alle Cache-Layer.
+
+**Verwendung**:
+```php
+use App\Framework\LiveComponents\Cache\CacheInvalidationStrategy;
+
+$strategy = $container->get(CacheInvalidationStrategy::class);
+
+// Komplettes Component invalidieren (State + Slots)
+$result = $strategy->invalidateComponent($componentId);
+
+if ($result->success) {
+    // ['state', 'slots'] invalidiert
+}
+
+// Nur Slots invalidieren
+$result = $strategy->invalidateComponentSlots($componentId);
+
+// Einzelner Slot
+$result = $strategy->invalidateSlot($componentId, 'header');
+
+// Template Type (alle Templates von Typ)
+$result = $strategy->invalidateComponentType('card');
+
+// Template Variant
+$result = $strategy->invalidateVariant('card', 'compact');
+```
+
+**Smart State-Change Invalidation**:
+```php
+// Invalidiert nur betroffene Caches
+$result = $strategy->invalidateOnStateChange(
+    componentId: $componentId,
+    oldState: $oldComponentState,
+    newState: $newComponentState
+);
+
+/*
+Prüft State Keys die Slot-Rendering betreffen:
+- sidebarWidth
+- sidebarCollapsed
+- isOpen
+- padding
+- theme
+- variant
+
+Nur wenn diese sich ändern → Slot Cache auch invalidieren
+*/
+```
+
+**Bulk Invalidation**:
+```php
+// Viele Components auf einmal
+$componentIds = [$id1, $id2, $id3, ...];
+$result = $strategy->invalidateBulk($componentIds);
+
+// Result enthält Success-Count
+// reason: "bulk_invalidation:150/200" (150 von 200 erfolgreich)
+```
+
+**Nuclear Option** (mit Vorsicht!):
+```php
+// ALLE LiveComponent Caches löschen
+$result = $strategy->clearAll();
+
+// Use Cases:
+// - Deployment
+// - Major Framework Updates
+// - Debug/Development
+```
+
+## Performance Metrics System
+
+### Metrics Collector Setup
+
+```php
+use App\Framework\LiveComponents\Cache\CacheMetricsCollector;
+use App\Framework\LiveComponents\Cache\MetricsAwareComponentStateCache;
+
+// DI Container Setup
+$metricsCollector = new CacheMetricsCollector();
+$container->singleton(CacheMetricsCollector::class, $metricsCollector);
+
+// Metrics-Aware Caches registrieren
+$stateCache = new ComponentStateCache($frameworkCache);
+$metricAwareStateCache = new MetricsAwareComponentStateCache(
+    $stateCache,
+    $metricsCollector
+);
+
+$container->singleton(ComponentStateCache::class, $metricAwareStateCache);
+```
+
+### Metrics Abrufen
+
+```php
+// Metrics für spezifischen Cache-Typ
+$stateMetrics = $metricsCollector->getMetrics(CacheType::STATE);
+
+echo "State Cache Hit Rate: " . $stateMetrics->hitRate->format(2); // "85.50%"
+echo "Average Lookup Time: " . $stateMetrics->averageLookupTimeMs . "ms";
+echo "Performance Grade: " . $stateMetrics->getPerformanceGrade(); // "A"
+```
+
+### Performance Summary
+
+```php
+$summary = $metricsCollector->getSummary();
+
+/*
+[
+    'overall' => [
+        'cache_type' => 'merged',
+        'hits' => 1500,
+        'misses' => 200,
+        'hit_rate' => '88.24%',

+        'performance_grade' => 'A'
+    ],
+    'by_type' => [
+        'state' => [...],
+        'slot' => [...],
+        'template' => [...]
+    ],
+    'performance_assessment' => [
+        'state_cache' => [
+            'target' => '70.0%',
+            'actual' => '85.50%',
+            'meets_target' => true,
+            'grade' => 'A'
+        ],
+        'slot_cache' => [
+            'target' => '60.0%',
+            'actual' => '72.30%',

+        ],
+        'template_cache' => [
+            'target' => '80.0%',
+            'actual' => '91.20%',
+            'meets_target' => true,
+            'grade' => 'A'
+        ],
+        'overall_grade' => 'A'
+    ]
+]
+*/
+```
+
+### Performance Monitoring
+
+```php
+// Check ob Caches underperforming sind
+if ($metricsCollector->hasPerformanceIssues()) {
+    $warnings = $metricsCollector->getPerformanceWarnings();
+
+    foreach ($warnings as $warning) {
+        $logger->warning($warning);
+        // "State cache hit rate (65.00%) below target (70.0%)"
+    }
+
+    // Alert Operations Team oder Auto-Tuning triggern
+}
+```
+
+### Metrics Export für Monitoring Tools
+
+```php
+// Export für Prometheus, Grafana, etc.
+$export = $metricsCollector->export();
+
+/*
+[
+    'timestamp' => 1678901234,
+    'metrics' => [
+        'overall' => [...],
+        'by_type' => [...],
+        'performance_assessment' => [...]
+    ]
+]
+*/
+
+// An Monitoring-Service senden
+$monitoringService->sendMetrics($export);
+```
+
+## Integration Beispiele
+
+### Beispiel 1: Card Component mit Caching
+
+```php
+final readonly class CardComponent
+{
+    public function __construct(
+        private ComponentStateCache $stateCache,
+        private TemplateFragmentCache $templateCache,
+        private TemplateRenderer $renderer
+    ) {}
+
+    public function render(ComponentId $componentId, ComponentState $state): string
+    {
+        // 1. Try State Cache
+        $cachedState = $this->stateCache->retrieve($componentId, $state);
+
+        if ($cachedState !== null) {
+            $state = $cachedState; // ~70% schneller
+        } else {
+            $this->stateCache->storeWithAutoTTL($componentId, $state, 'card');
+        }
+
+        // 2. Try Template Cache mit Remember Pattern
+        return $this->templateCache->remember(
+            componentType: 'card',
+            data: $state->toArray(),
+            callback: fn() => $this->renderer->render('card.view.php', $state->toArray()),
+            variant: $state->get('variant', 'default'),
+            ttl: Duration::fromHours(2)
+        );
+    }
+}
+```
+
+### Beispiel 2: Nested Component mit Slot Caching
+
+```php
+final readonly class LayoutComponent
+{
+    public function __construct(
+        private SlotContentCache $slotCache,
+        private SlotManager $slotManager
+    ) {}
+
+    public function render(ComponentId $componentId, array $slots): string
+    {
+        // 1. Check Slot Cache - Batch Operation
+        $cachedSlots = $this->slotCache->getBatch(
+            $componentId,
+            array_keys($slots)
+        );
+
+        $resolvedSlots = [];
+
+        foreach ($slots as $slotName => $slotContent) {
+            // 2. Use cached oder resolve fresh
+            if (isset($cachedSlots[$slotName])) {
+                $resolvedSlots[$slotName] = $cachedSlots[$slotName];
+            } else {
+                $resolved = $this->slotManager->resolveSlot($slotName, $slotContent);
+                $resolvedSlots[$slotName] = $resolved;
+
+                // 3. Cache for next time
+                $this->slotCache->storeResolvedContent(
+                    $componentId,
+                    $slotName,
+                    $resolved,
+                    Duration::fromHours(1)
+                );
+            }
+        }
+
+        return $this->renderLayout($resolvedSlots);
+    }
+}
+```
+
+### Beispiel 3: Dynamic Component mit Smart Invalidation
+
+```php
+final readonly class DynamicFormComponent
+{
+    public function __construct(
+        private ComponentStateCache $stateCache,
+        private CacheInvalidationStrategy $invalidationStrategy
+    ) {}
+
+    public function updateState(
+        ComponentId $componentId,
+        ComponentState $oldState,
+        ComponentState $newState
+    ): void {
+        // 1. Smart invalidation - nur betroffene Caches
+        $result = $this->invalidationStrategy->invalidateOnStateChange(
+            $componentId,
+            $oldState,
+            $newState
+        );
+
+        // 2. Store new state
+        $this->stateCache->storeWithAutoTTL(
+            $componentId,
+            $newState,
+            'dynamic-form'
+        );
+
+        // Log invalidation result
+        $this->logger->info('Cache invalidated', [
+            'component_id' => $componentId->toString(),
+            'invalidated' => $result->invalidated,
+            'reason' => $result->reason
+        ]);
+    }
+}
+```
+
+## Performance Best Practices
+
+### 1. Use Auto-TTL Methods
+
+```php
+// ✅ Good - Auto-optimierte TTL
+$cache->storeWithAutoTTL($componentId, $state, 'counter');
+
+// ❌ Avoid - Manual TTL kann suboptimal sein
+$cache->store($componentId, $state, Duration::fromHours(24)); // Zu lange für counter
+```
+
+### 2. Batch Operations für Multiple Slots
+
+```php
+// ✅ Good - Batch Operation
+$cache->storeBatch($componentId, [
+    'header' => $headerHtml,
+    'footer' => $footerHtml,
+    'sidebar' => $sidebarHtml
+]);
+
+// ❌ Avoid - Einzelne Calls
+$cache->storeResolvedContent($componentId, 'header', $headerHtml);
+$cache->storeResolvedContent($componentId, 'footer', $footerHtml);
+$cache->storeResolvedContent($componentId, 'sidebar', $sidebarHtml);
+```
+
+### 3. Remember Pattern für Templates
+
+```php
+// ✅ Good - Remember Pattern
+$html = $cache->remember($type, $data, fn() => $this->render($data));
+
+// ❌ Avoid - Manual get/store
+$html = $cache->get($type, $data);
+if ($html === null) {
+    $html = $this->render($data);
+    $cache->store($type, $html, $data);
+}
+```
+
+### 4. Smart Invalidation
+
+```php
+// ✅ Good - Smart invalidation
+$strategy->invalidateOnStateChange($id, $old, $new);
+
+// ❌ Avoid - Always invalidate all
+$strategy->invalidateComponent($id); // Invalidiert auch wenn nicht nötig
+```
+
+### 5. Content-Hash Based Caching
+
+```php
+// ✅ Good - Auto-invalidation bei Content-Änderung
+$cache->storeWithContentHash($id, $slotName, $content);
+
+// ❌ Avoid - Manual invalidation tracking
+$cache->storeResolvedContent($id, $slotName, $content);
+// ... später manuell invalidieren müssen
+```
+
+## Monitoring Dashboard Beispiel
+
+```php
+final readonly class CacheMonitoringController
+{
+    public function dashboard(Request $request): ViewResult
+    {
+        $summary = $this->metricsCollector->getSummary();
+
+        return new ViewResult('cache-dashboard', [
+            'overall_stats' => $summary['overall'],
+            'state_cache' => $summary['by_type']['state'],
+            'slot_cache' => $summary['by_type']['slot'],
+            'template_cache' => $summary['by_type']['template'],
+            'assessment' => $summary['performance_assessment'],
+            'warnings' => $this->metricsCollector->getPerformanceWarnings(),
+            'has_issues' => $this->metricsCollector->hasPerformanceIssues()
+        ]);
+    }
+}
+```
+
+## Troubleshooting
+
+### Problem: Niedrige Hit Rate
+
+**Symptom**: Hit Rate < Target (70%, 60%, 80%)
+
+**Lösungen**:
+1. **TTL zu kurz**: Erhöhe TTL mit Auto-TTL Methods
+2. **Zu viele Invalidations**: Prüfe Smart Invalidation Logik
+3. **Cache Size zu klein**: Erhöhe Cache Capacity
+4. **Variant Explosion**: Reduziere Template Variants
+
+### Problem: Hohe Average Lookup Time
+
+**Symptom**: Lookup Time > 1ms
+
+**Lösungen**:
+1. **Cache Driver langsam**: Wechsle zu Redis statt File Cache
+2. **Große Payloads**: Komprimiere cached Data
+3. **Netzwerk Latency**: Use lokalen Cache statt remote
+
+### Problem: Memory Issues
+
+**Symptom**: Out of Memory Errors
+
+**Lösungen**:
+1. **Cache Size explodiert**: Implementiere LRU Eviction
+2. **TTL zu lange**: Reduziere TTL für rarely-used Components
+3. **Zu viele Variants**: Consolidate Template Variants
+
