## 📈 **PERFORMANCE ANALYSIS**

### ⚡ **DATABASE PERFORMANCE**
```sql
-- Queries analisadas
SELECT * FROM wp_kc_appointments WHERE doctor_id = ? AND date = ?; -- ✅ Indexed
SELECT * FROM wp_kc_patients WHERE email LIKE ?; -- ⚠️ Needs index
SELECT COUNT(*) FROM wp_kc_clinics; -- ✅ Fast
```

**Otimizações Recomendadas**:
1. **Indexes**: Adicionar em colunas frequentemente pesquisadas
2. **Query Optimization**: Usar LIMIT em consultas paginadas
3. **Connection Pooling**: Considerar para alta concorrência

### 🚀 **API RESPONSE TIMES** (Estimativa Local)
- **Auth endpoints**: ~50-80ms ✅
- **CRUD operations**: ~80-120ms ✅  
- **Complex queries**: ~150-250ms ⚠️
- **Bulk operations**: ~300-500ms 📋

### 💾 **CACHING STRATEGY**
```php
// Recomendações implementáveis:
- WordPress Transients para consultas frequentes
- Object caching para dados de sessão
- HTTP caching headers para responses estáticas
- Database query caching
```

## 🔒 **SECURITY DEEP DIVE**

### ✅ **VULNERABILITIES SCAN**
