Laravel Performance

Laravel Performance Audit

Ziel: Jede Seite unter 2 Sekunden (TTFB 500ms | | FCP | 2.0s | | LCP | 3.0s | | CLS | 0.25 | | INP | 500ms | | Page Size | 1.5MB | | Requests | 50 | | DB Queries/Request | 30 |

Workflow

1. MESSEN → Baseline (vorher)
2. BACKEND → Queries, Caching, PHP
3. FRONTEND → Assets, Bilder, Fonts
4. SERVER → OPcache, Compression, CDN
5. MESSEN → Nachher vergleichen
6. REPORT → Verbesserungen dokumentieren

1. Baseline messen

# Laravel Debug Bar aktivieren (nur lokal!)
# Oder: php artisan debugbar:enable

# Response-Zeiten messen
curl -o /dev/null -s -w "TTFB: %{time_starttransfer}s\nTotal: %{time_total}s\n" {URL}

# DB Queries zählen (Telescope oder Debugbar)

2. Backend-Optimierung

N+1 Queries finden und fixen:

// VORHER (N+1)
$posts = Post::all();
$posts->each(fn($p) => $p->author->name);

// NACHHER (Eager Loading)
$posts = Post::with('author')->get();

Caching:

Cache::remember('key', 3600, fn() => expensiveQuery());

// Laravel Caches
php artisan config:cache    // Config
php artisan route:cache     // Routes
php artisan view:cache      // Views
php artisan event:cache     // Events

Indexes: EXPLAIN auf langsame Queries, fehlende Indexes in Migration hinzufügen.

DB-Tuning (große Tabellen >1M Zeilen):

• Partitioning nach Datum
• Read Replicas für SELECT-lastige Apps
• Connection Pooling (ProxySQL/PgBouncer)

3. Frontend-Optimierung

Vite:

// vite.config.js – Code Splitting
build: { rollupOptions: { output: { manualChunks: { vendor: ['alpinejs'] }}}}

Bilder: WebP/AVIF, lazy loading (loading="lazy"), richtige Größen (srcset), Spatie MediaLibrary Conversions.

Fonts: Lokal hosten, font-display: swap, nur benötigte Weights, preload im ``.

CSS/JS: Purge unused CSS (Tailwind macht das), defer/async für Scripts.

4. Server-Optimierung

OPcache: opcache.enable=1, opcache.memory_consumption=256, opcache.jit=1255

Compression: Brotli > Gzip in nginx/Apache.

Cache Headers:

# Vite Assets (hashed filenames)
Cache-Control: public, max-age=31536000, immutable

# HTML
Cache-Control: no-cache

CDN (Cloudflare empfohlen):

• Image Optimization (WebP), Brotli, Page Caching
• DSGVO: Cloudflare mit EU-Rechenzentren konfigurieren

5. Monitoring

• Sentry – Error + Performance Monitoring
• Lighthouse CI – Automatische PageSpeed-Reports in CI
• Laravel Telescope – Query/Request Profiling (nur lokal)

Pest Performance-Tests

it('homepage responds under 500ms', function () {
    $start = microtime(true);
    $this->get('/')->assertOk();
    expect(microtime(true) - $start)->toBeLessThan(0.5);
});

it('homepage uses less than 15 queries', function () {
    DB::enableQueryLog();
    $this->get('/');
    expect(DB::getQueryLog())->toHaveCount(lessThan: 15);
});

Report-Format

# Performance Report – {Projekt}

| Metrik | Vorher | Nachher | Budget |
|--------|--------|---------|--------|
| TTFB   | 450ms  | 120ms   | <200ms |
| LCP    | 3.2s   | 1.8s    | <2.0s  |
| Queries| 47     | 8       | <10    |
