## 🚀 Performance Optimization Strategies

### 1. Database Optimization

#### Connection Pooling
```yaml
# config/database_optimization.yaml
database:
  pooling:
    enabled: true
    min_connections: 5
    max_connections: 20
    connection_timeout: 30
    idle_timeout: 300
    
  query_optimization:
    enabled: true
    query_cache: true
    index_optimization: true
    analyze_queries: true
    
  performance:
    batch_size: 1000
    prefetch_rows: 100
    fetch_size: 1000
```

#### Query Optimization
```python
# Database query optimization
class DatabaseOptimizer:
    def __init__(self, db_connection):
        self.db = db_connection
    
    def optimize_queries(self):
        """Optimize database queries"""
        # Enable query cache
        self.db.execute("SET query_cache_type = ON")
        self.db.execute("SET query_cache_size = 268435456")  # 256MB
        
        # Optimize for reads
        self.db.execute("SET innodb_read_io_threads = 8")
        self.db.execute("SET innodb_write_io_threads = 4")
        
        # Buffer pool optimization
        self.db.execute("SET innodb_buffer_pool_size = 1073741824")  # 1GB
        
        # Log optimization
        self.db.execute("SET innodb_log_file_size = 268435456")  # 256MB
        self.db.execute("SET innodb_log_buffer_size = 16777216")   # 16MB
    
    def analyze_slow_queries(self):
        """Analyze slow queries"""
        slow_queries = self.db.execute("""
            SELECT query_time, lock_time, rows_sent, rows_examined, sql_text
            FROM mysql.slow_log
            WHERE query_time > 1.0
            ORDER BY query_time DESC
            LIMIT 10

    def optimize_memory_usage(self):
        """Optimize memory usage"""
        import gc
        import psutil
        
        # Force garbage collection
        gc.collect()
        
        # Get memory usage
        process = psutil.Process()
        memory_info = process.memory_info()
        
        # Optimize if memory usage is high
        if memory_info.rss > self.cache_size_limit:
            self.clear_cache()
            gc.collect()
        
        return memory_info
    
    def implement_object_pooling(self):
        """Implement object pooling for frequently used objects"""
        class ObjectPool:
            def __init__(self, create_func, max_size=100):
                self.create_func = create_func

                # Execute function and cache result
                result = func(*args, **kwargs)
                self.redis_client.setex(
                    cache_key,
                    ttl or self.default_ttl,
                    pickle.dumps(result)
                )
