Enabling jumbo frames on the gateway, as the correct answer suggests, involves allowing larger packet sizes to be transmitted, which can significantly improve overall network throughput by reducing the number of packets needed. This method efficiently addresses the high traffic volume between the database and web servers, specifically by enhancing data transport efficiency across the network. Though it may not resolve all congestion issues permanently, it's a feasible initial approach to mitigate the immediate network traffic overload. Additionally, it's crucial to verify network configuration to ensure compatibility with jumbo frames.
