Which feature can help optimize Security Gateway performance in high traffic situations?

SecureXL is the feature that optimizes Security Gateway performance in high traffic situations. It is designed to enhance the processing speed of network traffic through acceleration techniques. By leveraging various optimizations such as connection and packet handling improvements, SecureXL significantly reduces the CPU load on the Security Gateway, allowing it to handle a greater volume of traffic efficiently.

In high traffic scenarios, SecureXL can offload processing tasks from the firewall's software to hardware, making it particularly beneficial for environments that require high throughput and low latency. Additionally, SecureXL can streamline TCP connection establishment, accelerate packet processing for established connections, and multiply the capabilities of the Security Gateway.

This optimization impacts overall network performance positively, ensuring that legitimate traffic flows seamlessly while still maintaining robust security measures. Other features like VPN, IPSec, and SmartEvent serve essential functions in security and monitoring but do not primarily focus on optimizing performance during high traffic situations.
